Advertisement Bots
As an unlucky individual, I have become plagued with so many friend requests from level 1 bots that I have to decline 2 to 3 friend requests every day I get on. I'm sure a good amount of the community has had to deal with this before as well. My suggestion is as follows:
Force a brand new account to play a game or two before they get to have friends. Some people would be very harshly against this, especially people who like making smurfs and people who are trying to play with a newbie friend. Well, that's why it's only one game. Would you want to play an entire game of league for each advertisement you sent to somebody? Didn't think so. Hopefully RIOT will head my request and realize that this is a problem that nobody talks about but many have.
