Having A9LH/ B9S or whatever method you use itself is not a ban reason, Nintendo can't detect these things. Having CFW is very unlikely the reason for these bans too, since we may didn't completely hide it, but there are factors, which are way easier to check for,like having installed illegitimate titles (FBI, HBL, freeShop, 3DSident, etc). They can easily find them, by checking for unknown titleIDs. It's easy for them to do this, collect data, log us and inspect the logs.Depending on whether people whose systems had [x,y,z] during periods [a,b,c], they probably got banned, this is not confirmed, but the basic idea of how people got banned. Either we search for the exact titleID which everyone would have needed in their system, which is almost impossible and unrealistic, or Nintendo, like I said, just searched for unknown titleIDs itself instead of for specific targets, both is possible. There are many ways of how they could check for them.We now know which domains to block in order to stay safe, based on what people said who sniffed the packages which are sent everyday. Blocking these still lets us play online, which itself probably isn't safe, since we don't know which servers the game connects to and which data they will send, we would have to reverse engineer every game for that and this wouldn't let us play online anymore.The data collection could have happened this morning, or it could have been months in the making.Another explanation might be that Nintendo didn't ban a few people on purpose so we can't find a pattern, but this sounds unlikely, doesn't it?We may be giving Nintendo too much credit for the banwave, when they could just have done it as an immature reaction to B9S, which some users already suspected. Why didn't they do that when A9LH was released? B9S is "worse" for them. We literally can have full control now, any system so far can be hacked with it and if NTRboothax ever becomes a thing, it might even be a bigger threat for them. This, again, is just speculation, we simply don't know why they did it, their only response was "that people have been using unauthorized software".Rafa, a very nice guy on our discord, not sure what his Temp name is, began to analyse the results from Aurora's poll (with the nice table I made ;p) and found out that they were not targeting a specific CFW. There is no SOLID proof for that, but it's statistically provable. Even if analysing everything from that poll ends up with everything being random, we could either not have enough/ not exact enough information, the "People whose systems had [x,y,z] during periods [a,b,c]" theory could be true or that Nintendo actually didn't ban everyone.Regarding the "unbans", we are sure that it is similar to the SuMo banwave, some people got a temporary ban, but most people probably got a permanent ban. But banning someone for 1 day, 2 days or 4 days makes no sense, right? It's not that I don't want to trust the people who've been claiming that, but there is just little to no proof for Nintendo unbanning them and not them unbanning themself. One explanation for getting unban might be, that these people injected another seed, doesn't matter for what reason, that seed got banned, they restored a NAND backup (which contained their old (unbanned) seed) and they weren't banned anymore, there is no proof for this either though, but a few people said they were unbanned after restoring a backup.If you make a NAND backup, system transfer to this console, can you still use the NAND backup or will it brick? If it worked, that might be another explanation.Temporary bans are the most realistic and most likely explanation though.The banwave seems to be over as there haven't been any greater amounts of ban reports in the past few days, right now, they could just be banning individuals for whatever reason, or maybe the banwave is not over, we don't know, sorry.Blocking the domains, disabling telemetry, not cheating online, never installing or playing unreleased/ out-of-region games, deleting the activity logs, backupping your seed and injecting another one until we can confirm it's over, factory resetting or removing everything that breaks their ToS are security measures you can take in order to not get banned (again), but doing all of this could make you seem suspicious.. or maybe not. Unbanning is still a thing, but stay safe regardless.This was my little write-up about the banwave. I would like to stress, that many of these infos are NOT (and probably can't be) confirmed! This is 95% speculation. I repeat, this doesn't have to be the truth! This is not an absolute solution or a fix, we might never get any of those..I would really like to thank rafa, Veranek, Zalexard, enMTW, funkymon and several others from the official inofficial GBATemp 3DS Banwave support server, the past week was very exciting and fun, it was really nice talking, theorising and discussing about the banwave with you guys (and girls) (Also they contributed most of the information from this, I'm not that smart).(This was written by me, so if there is any wrong information, it was my fault for including it. Please blame me for it and correct me.)You may have a few questions, which is probably why you are visiting this thread.Anyway, I made a small Q&A in order to answer some questions I saw people asking.(NOTE: These are speculation, since we can't 100% prove it, but the answers seem very likely and realistic imo):Q: Is my NNID banned too?A: No, this only bans your LocalFriendcodeSeed_B.Q: Is my Switch/ WiiU in danger, because my 3DS got banned?A: Rather not, these bans only apply to your 3DS and since the NNID isn't banned, your WiiU should be safe.Q: Are you sure X isn't causing these bans?A: Maybe, maybe not? I'm pretty sure that the info in my write-up is correct though, but it's only speculation. Feel free to check the "Other possible ban reasons" pastebin in the "Useful Links" list though.Q: Is this ban permanent?A: Probably. Multiple Nintendo reps have confirmed this now, but we should wait atleast 10 to 25 more days, so we can be sure. Some people seem to be unbanned though, so some bans may be temporary.Q: Can I unban my console?A: Check the "Useful Links" List, there is a link to an unbanning guide.Q: How can I stay safe?A: Check the "Useful Links" List, there is a link to a pastebin with instructions, a list of domains you can block and a link to Cthulhu, so you can clean your Activity Log.Q: How can I contribute?A: Even just posting information about your banned (or unbanned) console can help! Feel free to discuss or theorise in the thread, in PMs or on discords.Q: You made a mistake!A: Please correct me, so I can fix it!Q: I love you..A: I know.If you have any other questions, feel free to ask them.Useful Links:Unbanning Methods: https://gbatemp.net/threads/all-3-methods-to-get-unbanned-from-recent-ban-wave.450679/ Nintendo's ToS: https://www.nintendo.com/terms-of-use Nintendo's 3DS EULA & Privacy Policy: http://www.nintendo.com/consumer/info/en_na/docs.jsp List of Domains to block: https://gbatemp.net/threads/regarding-the-recent-3ds-banwave.471781/page-291#post-7346389 (Don't block the connection test domain!)Nintendo & Collecting Data: https://gbatemp.net/threads/regarding-the-recent-3ds-banwave.471781/page-277#post-7345664 Poll Results: https://docs.google.com/forms/d/e/1...I38qp5IVKlk6lSCK0zeMZvijUqrPIuw/viewanalytics Poll Results (table): https://mega.nz/#!Dkkj0bJI!GBW12aQFP-nFV_j80gWvwwd0XactCvnpIZeAQokCW2Q |- with Rafa's Analysis: https://mega.nz/#!v49myRZD!7y09cP5_0zsc1YG0U3xRLphxevfpta7M-RqjbeDqgHw Rafa's Results: http://i.imgur.com/7tU7dWX.png How To Stay Incognito: https://pastebin.com/FPAES6eA Cthulhu (Cleaning Activiy Logs): https://gbatemp.net/threads/release...ime-step-history-and-cached-icon-data.439485/ Other possible ban reasons: https://pastebin.com/B7Ts9v7d
