Cheating and playing fair - is a black and white. There is no "shades of gray" between them and you can't be a "almost no cheating" if you have only a multitap script for your mouse. If you are playing TDM and flying over the map or have just modified game sounds on drivers level for better positioning (like ASUS Sonic radar, for example) - you are a cheater.
The issue here is the difficulty to detect and prove the fact of someone's unfair playing, especially if a person "cheating in a smart way" and is well knowing the limitation of anticheat systems.
And if a low level player shoots SMG with prefire and kills whole squad with headshots - it is likely cheating, then in a case with a 140 level player, who played 4-6K hours - then there can be a lot of doubts.
To the point: IordX is a guy with >4K hours on a PC. But in some cases you can get a situation like a player is using ESP (wallhacking) and boosting his damage. Recent gameplay with him caused a doubt in his fairplay and I decided to initiate this thread. The funny thing is that on his videos at BattleLog profile (recently dated by the way) there are no such skills and even indirect evidence of ESP (will show below).
TDM on Golmud, hardcore. Tight and balanced gameplay (386 vs 376), we are winning. IordX is running from lower field via Power Lines uphill. I have noticed him (don't know a name yet), shooting with DMR but he survived. I informed my squad (4 of 5 are skilled and playing with K/D >2), all are near upper and lower buildings at the edge of the map, meeting him. The guy is a likely knows locations of players and damaging with devastating force. While loosing to us with about 380 vs 390, he made 8 kills in a single life, while entire squad was meeting him and was prepare to shoot. You can say that it is possible and it is, but check the video and see how precise he know where are players and how instantly he is killing.

Almost the same episode from second player:

Beginning of the same match: he perfectly knew location of a hidden player:

I am not sure whether it possible to increase the resistance to enemy damage with cheats, but yet again a strange things were happening with him a round earlier (2 examples), but with no one of other players:
Shooting him with another soldier simultaneously:

One body shot, one - headshot and only after second headshot he fall down:

Regarding his "proof of a clean play" on his Battlelog: he plays versus a very low level players. Snipers are standing still (magnum headshots). In an aggressive cases he behave not bad, but incomparable to the cases on another public games. And one thing happened really weird on his video: targeting to the head he shoot to the antena, blindly closed his view to the target, which indirectly prove that he is using ESP and shot to the marker (1:15):

(I made a copy of that video just in case he remove this from YT)
To summarize:
1. This gameplay on his "proving videos" are incomparable to his gameplay on public servers
2. There are indirect evidence that this guy is using ESP and damage modifiers.
3. His recent gameplay on his videos - are joke versus his gameplay on public servers.
4. Number of hours he played is not making him a clean player.
5. Pieces of evidence say that this player is likely use ESP, damage boosters and even possible some kind of enemy damage mod.
Would be good if other people can add their thoughts on him but I suggest to ban this guy.
