what is the maximum number of trolls you can have on your block list?

I can't seem to find the answer, but just in case you didn't know, blocking a player does not prevent them from being matched with you. It only mutes them and prevents them from sending you friend requests/game invites. The size of the list is pretty irrelevant because they don't need to stay on there typically, but if I get the answer I'll let you know.
