Focusing in on harassment of individuals.
There was a period when I noticed somebody being harassed by Ethereal. I said to the staff "I've been harassed by Ethereal multiple times in the past, and felt targeted negatively by him at least three times so please don't let him do this to this other person". The staff responded by saying they wanted to stop him from harassing me, which I agreed would be smart on reflection. He was not allowed to come into my threads, which was pretty minimal but yee. When he came into one of my threads and replied, he was banned. It felt kind of grimy, but it was the minimum and he didn't meet it. He's unbanned now so it feels okay to mention.
Recently, someone got mad at me for talking to them and so we set up the same ruling. I think that person is a lot happier knowing I won't come into their submissions or anything, but I also live in fear that I will accidentally.
I don't expect this post to get many upvotes because I shared herstory of history here, but it's important to me that people understand the reasoning behind what's stressed me out in the past and how I abide by it, even, in the present. People are allowed to say "I don't like the attention you're giving me" and have the other person back off. We're not in real life where someone can just leave the room if they don't like another person. We have to share this space together and I think it's perfectly alright for the people that just don't get along to not have a thing to do with one another.
I think there should be something clear in the rules about a "do not interact" clause for when you've gone overboard caring about another person's work on the site and need to cool it. For some people, it should extend to discord and for others, just replying in threads is the bare minimum to be met.
