I don't feel the "one-way mirror" thing as you say, is really leaving the doorway open to drama/trolling. If you hit ignore on them you can't see any of their stuff and they can't contact you through messages so if they DID want to try and start drama or troll you, it would have to be done publicly either somewhere onsite or in one of the two chats we have in which case one of two things will happen :
1 : Staff comes on the attempted troll/drama starting and deals with it.
2 : Another member comes across the attempted drama starting/trolling and reports it in which case staff steps in and deals with it. Could they say things behind your back in the conversations area to other people or in a private DM on discord? Yes, but that would still be a thing even if they couldn't see your content.
I feel the saying "It takes two, to tango" fits well with your worries about it leaving that door open; its really difficult to "stir the drama pot" with someone or troll them if they have you on ignore and can't even see it let alone respond.
Thats just my opinion on it based on everything I've kind of seen or dealt with.
