What confirmation? I am neither a user or a developer of the bot. I also have not been banned by Valve's decision to ban usernames either. My affiliation is to the extent of creating an issue on their github repository. Why are you making such unfounded accusations?
Yes, I commented on the issue. No, I am not affiliated with the bot. I'm not pretending to be anything, I never claimed anything. If I wanted to hide anything I wouldn't use my main github account. I just thought that Valve banning based on usernames was an interesting subject, so I commented on it. You're commenting on a thread about cheaters, why would you do so? You're a living case of a criminal trying to pretend he's not a criminal after he's caught hands in!
Kisak, a Valve Employee, confirms that VAC bans are being handed out for usernames matching catbot. Yes, it was open and driven by the people that were banned because of a username.
I don't know any other anti-cheat that has used a blacklisted username as a mechanism. Valve did not bother to obscure any part of this mechanism, they publicly confirmed that this mechanism was banning people due to their name. This is an open source cheat that has not generated any revenue, and it was worked around as soon as it was identified. Regardless, saying that this changes nothing is ridiculous, this mechanism was aimed mostly at cheaters, with some innocent in the crosshairs. Now, all cheaters have worked around this and only innocent are left in the crosshairs.
Innocent users are the only ones that will get caught up by this anymore, the cheaters already worked around this(https://github.com/nullifiedcat/catbot-setup/commit/c2d22ee9...). Yes, cheaters were the first to report it because they were the first to experience it.
