This has been happening to me and others as well, across multiple Lemmy instances. The common thread seems to be Firefox. I assume something changed in a recent Firefox update?
If anyone figures out the root cause, I would love to hear about it.
For the curious, here's the thread OP is referring to: https://lemmy.world/post/18504118
Looks for the comments by MrKaplan.
For each community that banned you, you need to send a message to one of the mods in that community. The modlog shows that you are currently banned from !asklemmy@lemmy.ml and !asklemmy@lemmy.world. Go to each of those communities, look in the community's sidebar, and you will see the names of the community mods. Click on one of the mods' names, hit the Send Message button in their profile, and say your piece. It's up to them to decide if they want to unban you.
Are you using an app, or a browser? I'm wondering if you have some open reports from the communities you moderate. Apps generally don't handle reports well, and some mix them in with private messages.
Edit: Nevermind, I checked the reports queue. Still, it would be helpful to know what interface you are using.
FYI, I finally locked !soccer@lemmy.world. One user was still posting there occasionally, and I wanted to give them an opportunity to comment. I haven't heard seen any objections for almost a month so I figured it was time to do the deed.
I'm hesitant to take a community from an existing moderator and hand it to a new user who has only been on Lemmy for a few days. I suggest you start by interacting for a while - make posts, try to drive discussions, get a feel for this place and how it works - before jumping into moderating multiple communities.
