Looool...

Welcome back to the internet of the turn of the millennium.

Policy? There almost certainly isn't one. This is the internet that isn't controlled by a corporation so I'd assume that it's the same as the old internet from before that happened.

Nobody is likely to be giving a shit here, just like none of us gave a shit before

Basic rules would likely be, don't be a POS and you'll be fine, just like it always was. Nobody's going to care about your alts if they're not being total cunts to everyone.

And yes, this means that I clearly don't know the answer to your question in absolute terms, and yet I'm answering anyway (I know right, fuck me), but having looked around here, I'm seeing a place that's run by normal people, just like the internet was always run before everything got silo'd into vast corporate web platforms. I'm pretty confident that it works the same way.

If so, the policy would be, "do whatever you want, but don't be a shit".
