I sent the MOD this message:
Hi XXXXXXXX, I just noticed that you banned me 2 hours ago from c/Science for Spam. I am confused. I mostly lurk and haven’t commented or posted anything in several months. I definitely don’t post ads or spam. Can you please let me know what happened?
The only reason that I noticed that I am banned is that I watched that (long-ish) video about Brainrot on the feed and the top comment is asking for a tldw.
No, there’s plenty they can do. They’re the developers of Lemmy itself, they could easily implement something that limited the interaction of external users. Some instances already have downvotes disabled entirely. But I guess they get off on this.
