It's just an auto-invite linkshell. Outside of harsh moderation from SE to keep it purely as an informative network, that's all it'll ever be.

Sometimes the noise can be nice to have. But I also don't think it's worth caring about that much; if it's somehow destroying the new player experience I'd honestly say delete it. If it's egregious chatter, you can report it. Either way, in most I've been in someone'll usually get an answer to their question despite the topic of conversation when asked. So it's usually... kinda harmless.

Plus, tbh, "Online Interactions are not rated" is... a real thing. And if it's not egregious enough for a GM to action or handle, tbh, I don't know why any normal person would... care.

Anyway;

Not like you can't use google anyway to get a direct answer on basically any question about the game if you're somehow stuck. And the mentor program is kind of a general failure. So, yeah, delete it would be my solution.
