Quinn is a professional gamer! He does this for a living, and he does not use bots. It is sort of like stealing from your place of employment, it is not worth the risk of losing your income if you get caught. Not everyone with high paragon levels and in the top ten bot! Most people have the misconception that everyone that is higher than they are or better than they are bot, and that is not so!
I think quin is a good streamer and in no way botting. Hes on alot and if you follow his guides and spreadsheets etc... The guy does know his stufff. Sorry but think you're on your own with this post. Cant say the same for those that did get banned but was pretty happy about some of them
Considering that Quin has regularly provided in-depth data on in-game mechanics, and has constructed multiple LB-worthy builds, I think it is clear that he was actively playing the game. Personally, he is the only streamer I actually pay any attention to (I don't exactly make a habit of following streamers), as he gives a strong impression that he knows his sh*t through and through. It becomes quite clear from Quin's build explanations that he has definitely play-tested them before releasing them, as he understands the strengths AND weaknesses of the build; i.e. do x now, but don't do y, because z.
Obviously there is nothing in this post to actually prove that Quin is 100% legit, but I will say this much:
Quin invested a substantial portion of his own time into the game, as an ACTIVE PLAYER.
Quin provided significant contributions to the community; constructing, testing and explaining a variety of builds, so that OTHER PLAYERS could benefit from them. IMHO these are not the actions of somebody who hogs the competition, and certainly not an example of malicious intent.
