Something similar happened to me in the Spanish chat where i responded to someone who said hello to me, i mentioned the weather and i was muted with a "no spamming" warning. I have no idea why. I became very angry because i found it very arbitrary and i wanted to file a formal complaint. I was unmuted while having this conversation with support, and they directed me to submit a complaint to the communitycomplaints email, which i won't because i'm not angry anymore.
Best of luck to you.
