Bots in Dominion and TT?

First off I am not sure if this is the correct forum, I haven't played actively or visited the forums in a few years, so I am still getting accustomed to all the new changes. ^^;

But anyway, I came here asking if there is a proper way to report the program controlled accounts that I encounter quite often in Dom and TT? I have just been reporting them after the game under "Assisting enemy team", but I am not sure if there is a better way to really get someone at Riot to look at these accounts and get them off the servers.

These are game modes that I really had fun with and enjoyed in the past, but recently when I have tried playing them I almost always encounter a high amount of Bots, and that just isn't cool.
