Getting shot around corners or bullets not dealing damage in no way make me think cheater. Those are netcode issues. Even teleporting or invisible characters do not make me think cheating. Those are all probably netcode or software bug related.
Cheating is when a player constantly has awareness of every other player on the battlefield and no risk of rushing in without checking corners because they can see the entire enemy team location via ESP/Wallhack at all times. Or insane accuracy with SMG on every engagement, out-of-whack HSK ratio, tracking targets through walls (non-paik), etc. There are big differences in symptoms of a cheater vs. netcode related issues.
For me it's simple: cheaters?...hmm maybe. Totaly broken netcode/hittreg/ttd/ttk etc.etc?...one big YES!!!
