One of the things I've watched shift drastically over the years -- it's one of those pendulum issues in the hobby that seems to swing from one extreme to the other -- is how people handle bad actors on games.
We know, collectively, that there are some toxic folks in the hobby, or folks who commonly demonstrate some exceptionally toxic behavior for whatever reason. (Some of these reasons may be more understandable or sympathetic than others, but that's a separate issue, and this one has plenty already. The reasons why may be good fodder for another thread, but aren't meant to be the focus here.)
How would you define or identify bad behavior?
How much bad behavior would it take for you to identify someone as a bad actor (rather than 'the average person who screws up sometimes and generally will feel bad about it when they realize that they have done so, and try to make it right')? Does it have to be a specific sort of behavior to cross this line?
How do you feel it best to handle known bad actors (by your own definition as above, there's no need for broad consensus that someone is problematic, ex: Spider/Rex/Elsa/Custodius/etc.) being allowed access to a game at the outset? Pre-bans? Pre-bans for some, new chance for others? New chance for everyone?
If -- either because they were allowed on under a new chance principle, or snuck on, or never realized they weren't welcome in the first place and just showed up -- a bad actor appears on the game, how do you handle this? This is from the player, staff, and general perspective (if they're the same for both). This can be anything from 'ignore it' to 'ban instantly' to 'keep an extra eye on them' to 'avoid them' to anything else you can think of.
As staff, how do you want players to handle this? As a player, how would you want staff to handle this? (Not actually the same question as above.)
Do you have concerns that the presence of a bad actor on a game will inspire bad behavior in others? (This can be through following that person's behavior model, or starting a gossip circle, or spawning arguments somewhere that spill all over the game, etc.) If so, at what point does this become an issue in its own right, and what do you do about it?
This is in constructive for a reason; please keep this in mind! While examples of bad behavior are very likely going to come up, this is not a place for specific call-outs re: game behavior; please try to provide examples without naming names if you can. (Doubly helpful, because not all of us have direct experience with any of the various problem children in the hobby, so knowing the bad actions really is more important than knowing who the bad actor is.)
