If you insult them in the right way, you can get them to leave.
If they're using VIP hacks, they're paying for them. Paying $20 a month to hold a button and "own" everybody on an online game where the only aspect of it that makes it fun is that fact that you go around to shoot people is just lifeless and stupid. If they have nothing better to do than sit there and "own" with their downloaded "skills" in their lives, then they need to get ripped off the computer and duct-taped to a tree until they hear a heartbeat. I mean honestly, what kind of person actually WANTS to come into a map and hold the left mouse button on a group of people you know couldn't even get close to killing you? Sure, the power would get to you for maybe the first five minutes. After that I'd actually want to go have some fun by actually using my own skill to kill other people that aren't that easy of which to dispose.
Just hit them with stuff like that and they'll realize that they're wasting their time and money and probably go legit. However, there are those occaisonal noobs that actually don't have anything better to do and will sit there and ignore you, and say that they did your mom last night and you're a crying little baby. In that case, just tell them that you know that they know that they're wasting their life away by paying $20 a month to hold down a button and masturbate over their own "skill," and then leave.
I wish ignorant pieces of **** like this could be dealt with in the same ways as some of the people on Maplestory who bothered me, like dexless sins who would come into my map and just ks the crap out of me for 2 hours until I realized I was wasting my time sitting there trying to defend myself, and so were they. With those noobs, you can just ask your friend Alex to change their secret information for two months and watch as they scream at you to give it back on some other account, because they knew it'd be you after you warned them what you were going to do to them and they still didn't stop. :O
Yeah, some of my feelings about VIP hackers and other ignorant little shriveled up ***ches seeped into this reply. :/
