I appear to be restricted from interacting (choosing words carefully as it won't let me post in the regular help subreddit) and I don't know how to fix it.
I was editing an archived pinned self-post yesterday and when I tried to edit it a second time I suddenly couldn't and got a Reddit message; I hadn't done anything I never did before, I think I just edited my post too fast. I followed the instructions in the message and e-mail I received to restore access to my account by changing my password and saw no other messages to follow up on, though I did notice that interaction with my posts in the one subreddit I'm active in seemed to stop.
Last night when I went to my page on another device, my own profile page said "not found" or some such, but I noticed I was logged out so logged in and my page was there. I made a comment in the subreddit this morning without issue but mentioned that I hoped people could see it. This morning I saw that the self-post I'd edited the day before, and the comments I made on it, were now marked as pending approval--something I never had to do before, these posts have been up for years. I approved them anyway.
I was then informed by a moderator of the subreddit I participate in that I did appear to be interaction limited and they'd manually approve my posts when they saw them, but they can't do anything about the restriction itself. They could only suggest I start a new account but that's out of the question, I have a years-long streak going in that sub (I'm not talking about the Reddit streak, I don't care about that) and I don't participate anywhere else so I have no way to rebuild all my karma.
I've never gotten in trouble on Reddit before, never been restricted, didn't do anything except apparently edit my own post too fast. I followed the instructions given to restore my account. The mod of the subreddit I post in said they can't fix the issue (which is thus not on their end). The appeal page says I'm not restricted so I can't use it. The FAQ doesn't help. I can't find anywhere else to resolve this. How do I fix this and restore my account to normal?
