hmm what i understand that se is afraid of is pure spam report trolling legitimate players.
theres actually a solution to this.

if its made so you can only report spam on /tell's and friend requests it would be impossible to use this feature like a troll as u would have to send a godlly amount of tells to alot of people as well as friend requests to pick up enough trolls

to improve even more there should be a 5 friend request limit so no spammer can hit the entire server
