New account-naming conventions needed to prevent hashcodes

Riot, if you see an account with a suffix or prefix like this: kHgRe or some sort of alternating lowercase or uppercase lettering (and possible numbering, as well) when it doesn't spell out an actual word, you need to start banning these accounts proactively, and prohibit future accounts from using those types of alternating cases. These are bot accounts. I've had my games spoiled plenty of times by botting players on Twisted Treeline, and invariably, they use these types of hashcodes at the end or beginning of their names. I imagine it has something to do with how the scripts are coded and how they interface with the game. Of course, I report such bots, but they keep popping up, anyway.
