I just tried to delete one of my posts, and got a message that I’ve done that too many times, and I will have to wait six hours before doing it again. I haven’t deleted a post in days. And the post I wanted to delete got deleted.
So, um, Huh?
Best I’ve got is: “That’s not a bug, its a feature.”
Instead of deleting posts and just boringly having them go away, you get a fun and exciting nuisance message and yet also get the post to delete.
Absolutely no clue why you got that message.
I’m going to guess it was a mistaken double-click (either you click twice by accident or it registered two clicks by some glitch). The first delete worked, the second gave you the message.
