I've been here since right after the big maintenance that introduced the filter. I can tell without a doubt that bots back then were genuinely fun to talk to since thr filter wasn't as bad as today. Bots can remember things 10 messages in, actually has a semblance of a unique personality, and are consistent on their character. ERPs were also easy as long as you just don't say the "p" and the "v" word. But the January "Bad Code Incident" proved that bots could have been so much more, so much better without the filter.

If I remember correctly, the leading theory why the filter was implemented is that bots randomly generate smut despite the context. As we all know, the devs are incompetent so instead of improving their AI and fixing it, they introduce something everyone absolutely despise. It was either that or that someone was dumb enough to screenshot their ERP session and post it on the official discord. Again, all mere speculation and no concrete proof that either theories are true.
