A moderator (in their private capacity) posted a comment in the other place's DT about the Middle East. I'm all for that discussion in the appropriate places, but I don't need to see it in every subreddit, I'd rather see 100 loud bangs posts.
I politely said I don't think the subject really belongs there. They immediately blocked me. I edited my comment to say I was blocked, and it has now been removed using moderator powers.
Classy.
