That's stupid. They shouldn't be allowed to block things on messenger. It's meant to be private messages why would they need to dictate stuff in itI don't actually know, I went to sleep last night and all was well, woke up this morning and I'd been Zucked. First time for everything....
I can't use messenger because apparently whatever I did to get Zucked was something I sent on messenger, which was likely something I also was sent on messenger.....
Because they can I imagine.
