Since you are level 2 people will give you serious answers. Level 1 is probably a quick ban.
Warping, ghostkill/gank, making any npc a vender/banker, grabbing corpse from anywhere in the zone, looting any corpse from anywhere in zone, ect. Stuff like that requires MQ2 to change packets sent from your pc to the server. Sony/Daybreak payed a lot of money for a detection system that detects these altered packets so they can quickly ban the people using them.
In short the old game-changing hacks get your banned quick. You might find a coder who can update the old stuff if you throw enough money at them, but it would be only for a one way ticket into a ban.
The stuff this website (redguides) gives you allows you to skirt the line on what Daybreak lets slide by. You should be able to find whats acceptable and what will get you suspended if you search hard enough.
