What the hell is that kind of hack?

No delay hack edits wz file and removes the attack animation AFAIK. Hence their clients will NOT show your attacking animation. That's why you get lots of no-delay hackers calling others "hacker" ironically, because they cannot see your attacking animation.

Thank you GummyBear,

I understand what is going on now! I was in a party at the Windraiders when someone came in and accused the Hermit in our group of hacking. I know for a fact that is individual does not hack. The intruder started their hack and was intent on staying until we advised that we were reporting. I guess there are times when being in a trusted group comes in handy. All of us being in the same house, same room kinda helps with communication while playing. He apologized and left!
