Proposal
Details/background on your proposal
Roblox’s block feature is meant to prevent players from being able to join you. From what I’ve seen, this still works in instanced games such as Deepwoken that have a similar server system to Arcane Odyssey. What this would do is simply prevent people you have blocked from joining you; if a person tries to join via the teleport function on the main menu, an error message would pop up.
If a person tries to join another person in that server, though, they would still be able to get in. While this could be seen as a loophole and blocked off, I can see how certain people may not like being able to join their friends because they have one person in a server blocked.
Reason to add/change
Along with being able to avoid people you find toxic/annoying or just dont want in your server, this could help with avoiding future exploiters (but mainly the annoying people part).
