Pretty sure anyone who has played over ~12 hours a day in a season like this should either be seriously investigated or banned. This filter alone will be able to detect the majority of botters which make this issue a problem.
Botting is way more serious of a problem them most people would realise and alot of builds can easily bot like <5 minute GR 70's solo for huge exp, T11-13 for infinite keystones and ubers/bounties for perfect ancient gear. These botting programs are too advanced/ sophisticated to be ignored.
Fingers crossed for another MASSIVE ban wave at the end of the season, id rather have a dead game then one riddled with cheaters.
