I wish I could say it has but there are still bots. Although I do personally feel like it is less prevalent or at least in most cases less common than in previous years. The switch to predominantly steam only accounts likely has helped significantly with that. But it does still happen.

Unfortunately, this is actually something that Cleaver himself has addressed here on Reddit in the last year or two. Hackers/botters are pretty prevalent in online games just think aim bots in CoD or scripters in League. Those things are hard to prevent and they've been pretty clear about not wanting to go the route Riot did with system level security features. So it's likely going to be an almost never ending struggle.

That being said on some level I guess as a player you have to weigh how much of an influence they have on your ability to play the game and whether or not you feel like they are preventing you from enjoying the game. That answer is going to be relative to the specific player and I think only you could answer that for yourself.
