Kitboga is a scam baiter and occasional PC game streamer on Twitch. His goal is to spread awareness of the various phone scams out there, that prey upon innocent people that are too easily-manipulated into their schemes.

In other words, he prank calls scammers to try and go along with them, while trying to waste as much of their time as possible in the process. The most common scam seen are the infamous "tech support scams" — where users are coerced into calling (or, in many cases, cold called by) a fake tech support hotline (most commonly an Operator from India) that tries to convince the user that their computer is compromised and requires an expensive software subscription in order to fix it. Or it's the IRS trying to claim you owe them, or trying to give you a fake government grant.
