I'm pretty lax

Don't be a big meanie

Arguments are cool and all but don't resort to stuff like flamewars. No hard limits though.
Mark your lewds!

Reminder that lewd is bad and nobody wants to be forced to see that. Just mark it sensitive and anything goes
Keep it legal!

Server is hosted in france, keep content legal for there (+ wherever you're browsing from)
No ads/spambots

I didn't think I'd have to specify this, but please do not set up bots solely for trying to advertise.
Non-TOS recommendations

This is stuff that'd I'd like you to do, but I won't outright ban you if you don't follow them
- If someone is sadposting, don't antagonise them - they probably just want to vent
- Take things as if they were posted in good faith - unless it's obvious that they weren't
- Put walls of text behind a subject (CW) - helps the timeline not get flooded with text

So I guess yeah, that's about it. Try to be nice, eh? We're probably all sad here.
