bots sending friend requests

Hello community!

I've noticed the other day that I get a lot of friend invites of people I've never played with... Once I clicked on accept thinking that I already played with him and it instantly sent me a message telling that I can get free RP and tralalalalala..... and this guy, even tho he was connected, was not in my friends list. And it's like the 5th one I get this week, and the same thing happens to my friends. soo I'd like to know : Is it just general or is it only some isolated cases? I'm getting sick of those kappa

Here's a poro for the LoLz
