I'll give my example, although it's a bit out of place on my part...

/r/news locked/suppressed [0] as 'Politics'.

I sent a Message to modmail:

Me: Calling this 'politics' makes me ask who's on the an alphabet payroll... Just saying.

Reply from modmail: This message makes us think you haven't bothered to read the rules... Just saying.

Then I was muted from /r/new modmail for 28 days, while also being perma-banned from /r/news.

Months layer, I had left a normal comment on a different thread with a 'mobile' secondary account on /r/news, and found both my desktop and mobile accounts locked for 7 days because the /r/news comment was considered 'ban evasion'. Despite having otherwise commented on /r/news from my mobile account in the meantime with no repercussions.

It was within the subreddit rules and reddit TOC to do all of this, I acknowledge, at the same time it's almost like Reddit is hitting that vibe of StackOverflow from a few years ago where mods can just power trip and make the place less useful for everyone...
