I've been lurking for 6+ months, barely vote, no post or comment. I was banned for spam.

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.
