Hey GOS!
Just here to let you know, that being obvious while playing does not get you banned.
You can use full evade with 0 humanizers and bans, and still get banned just like before.
The Cheater report system is (currently) useless, and it does not affect bans. The only way you are banned for playing obvious, is if you play against a popular streamer/youtuber/rioter, and they manually submit a ticket to the staff members at Riot.
My source? 1 year of full blown obvious cheating. Using multiple accounts (With obvious scripts and with utilities only/no evade only, for example), and they both got banned during a banwave. No account of mine has been banned for being obvious, except once when I played against a Rioter in Diamond.
Reports are complete bull**** - I've been reported every single game for 5 months straight (while using another platform), and my account is still perfectly fine and alive.
