Here’s my use-case:
https://meta.discourse.org/t/docker-upgrade-failed-now-what/13838
By the end of that thread I was not allowed to post or PM anymore for 24 hours. I don’t think I did anything “wrong”, sure I could have edited instead of posted anew a few times but I don’t see anything there that should justify a user being blocked from posting.
Anyway do with it as you like, I’ve simply increased the limit of the setting for now, though in my opinion that is not an ideal solution.
