Can i block someone on ask?
It won't prove anything. Only thing blocking someone on ask.com does, is, it won't allow that "blocked" person to follow you. They'll still be able to answer and comment on your questions.
They have to be following you, then you click on them and theres a block option.
Yes. Go to their profile and hit block.
Most of your questions are deleted anyway troll. Everyone check out his profile and the questions he tried to ask that were removed.
Hope it isn't me Carp ;-)
got to person profile and block them
