Like, ban people from sending friend requests until level 5 or something. At least level 5. Allow me to see the level of the person that is sending me a friend request. If I see the person inviting me is level 1, I'm not going to accept it.
There are multiple things you could do to HELP with this issue, and I'm not sure why nothing is being done about it. Maybe it would take away from the time you set aside to fap to Zed's #LC$BIGPLAY$.

ActuallyArrow1 votesI had like 4 people friend request me. I added them because I thought they were people I knew from the forum, or PAX.
They were all lvl 1-3 trying to get me to help farm for Party Rewards on their smurf or something.
Nucleophilic atk1 votesI get constant elo boosting spams from level 1 accounts. They are doing nothing to stop this.
