In the last week, the team has released new versions with a suite of changes that will render invalid market attacks obsolete and incentivize highly liquid markets. You can read the post above in full for further context, but here is an excerpt from the writeup:

We believe that these changes will make Invalid market scams a losing game and ultimately obsolete. Invalid market scammers will face a choice: seek a new exploit, leave Augur, or start creating valid markets and contributing productive liquidity (it appears the most prolific Invalid market creator on Augur has already creating some valid markets). Either way, it’s a win. If they find a new exploit, we can counteract it before Augur hits primetime. If they redirect their skills at making valid markets, even better.

In the high-stakes face-off between a protocol and its exploiters, one invaluable edge that Augur has is a community of thousands of people the world over who are excited about the project and want it to succeed. The community has been instrumental in helping develop and refine some of these solutions. In particular, we owe a big shoutout to the folks in the #game-theory channel on the Augur Discord.

We also recognize numerous members of the Augur community who have gone out of their way to educate others on the risk of Invalid markets and in some cases to even front run scammers. And finally, while we could never condone their actions, thank you to Invalid market creators for showing us where Augur could be improved.
