I personally have never been banned for kitpvp/any pvp hacking.
But I do think for some of these people banned for kitpvp hacking, I do think it's kinda unfair, the staff do not have 100% solid proof of them hacking. Yes, videos showing obvious 'hacking' are a good thing but do the staff actually KNOW they're hacking? I mean do the staff have pictures of solid proof (like maybe a picture of their files) that the person may have a hack. A friend of mine was banned for Pvp related hacking a while back, and I saw the video of the hacking, but he didn't have any hacks.
So even though videos clearly show someone hacking, this isn't exactly 100% solid proof. 100% solid proof is when staff have seen the files of the supposed hacker.
