I know you can block someone from your projects, but when you block them entirely, do they still get to vote on your cast suggestions?
Will blocking someone prevent them from seeing any of my cast suggestions on this site?
They only can't vote on the ones in your story. If you post a suggestion on someone else's story, they can still vote on it.
It works with me, i got 2 guys who spams on my stories and i blocked them from ever contribute to my stories. The first spammer tho, i unblock him once to lure him out into contributing to one of my stories and after that, i blocked him. But i don't know about that "you can still vote on a blocked user's suggestion in someone's story" thing cause i've never been contributing on another story.
