AITAH for quote-on-quote "being a dick"? (Online experience)

I (14M) was watching a PG13 twitch streamer, I was watching the stream and I looked in the chat to see an emote of a fursona mastorbaiting. It was not his fursona. I reported it, and I will say, I did let them know. He was very upset. The next day I opened Twitch to not only find that I was banned from his channel but his BOYFRIEND'S as well. I was upset. I contacted a mod from both channels and he said "I did put everyone in a bad mood," and "the guy who I reported the emote from thinks someone has a vendetta against them." I did unban request, and fast forward to tonight. I got the unban request denied and the mod's note stated "You have demonstrated you are not mature enough for my content, you have repeatedly executed behavior that makes me feel uncomfortable, and you have broken rule #4. (Don't be a dick)"

My question is AITA for doing that? I feel like it's an everybody sucks thing myself
