We hired a team of trial moderators, and to allow them to "practice" we also hired some bots that do strange things and need to be moderated. Those bots are identified as "Mod fodder" in their title.
Test User is one of them, he likes to spam "bruh" everywhere. At least this is the only thread in which he isn't off-topic
This is worrying indeed. We hired the bots specifically for this job, and some regular users do the job better than them for free... Maybe they should be turned into regular members, nobody would notice
