This is the reason that we have a bot problem in League of Legends
Because Riot doesn't care about the bot problem. Here is my experience.
I ran into this player (see picture below) about 2 weeks ago. Long story short, he would pink the monster camp so he could continually aa-reset it and be able to afk without leaverbuster triggering him.

I reported this player, obviously, as it ruined the game for our top laner that had to 1v2. I sent in a support ticket to rito about this player.
Here is the awesome conversation that went on with rito guys:

Now, the problem is that this person was given 100% proof that the player was afking using the method that I had described, yet the rito guy wants to say they need to investigate the person. The proof was given 2 weeks ago. Once we got past the this is 100% an afk player hurdle, he then goes on to say that it IS punished. Excuse me, but I gave you 100% proof of this guy 2 weeks ago, and his match history (see below) shows him doing it for a long time before I even ran into him. So no, obviously you don't punish this behavior. If this player was punished, he wouldn't be doing it over and over and over again.....including a lot of times AFTER I gave you picture evidence of it happening. They want to continually say that they punish them, it just takes time to detect them. No. Players like me send in support tickets and nothing still gets done. Why? My only guess is because that account is one more account that will be sold to a banned player and they will probably buy skins on it.

TL;DR: We have a bot problem in this game because rito refuses to address and punish the players that are doing it.
