Hey there!
Definitely, some good points you made there. I agree that KitPvP is very understaffed, which is why we always encourage players to apply for staff, however, they do have to be qualified enough for this position. I, myself, try to get on as much as possible to deal with hackers, unfortunately, that hasn't been possible recently, due to other commitments. If no KitPvP staff is online we encourage players to use /report and /helpop to report hackers, as all reports are being passed on to us. If you are able to record, it's worth trying to get a clip of a hacker and then send it to us, put it in #reports on the discord or make a support ticket on the forums.
As for the anti-cheat, it's doing a decent job at detecting blatant hacks for now, but we are currently waiting on an updated/improved one. Please continue to /report and /helpop the hackers until then! :)
Sincerely,
Lavendel
