For a level 95, the best place to hack is really Crespo A. You can get tons of XP by spawning and killing Laiden Egos.
Hacks to use for Crespo A: Non-aggro, speed (self only), skill (if you have it), Vac (turn it on AFTER going through the first teleporter, or you will have a high chance of crash). Wall Hack is really unneeded, it saves you 2-3 minutes at most. The Vac hack is what causes Laiden to spawn egos like crazy. In order to kill Laiden in time, target him and the Egos will get hit by your AOEs.
Crevice is also a possibility, but can be a bit difficult. One trick to use in Crevice is to not stay at the end of a hall, but instead to stay close to the middle. The reason for this is that some monsters don't "see" your character at the end of the hall, so they just sit at their spawn point, building up until you pass 50 monsters.
Hacks to use for Crevice: Non-aggro (with speed for the monsters), skill. No need for vac or wall, the monsters already are set for high aggression.
If you don't want to pay out dil, Python is still the best place to hack. The ideal kill zones in python are the 2 open areas to either side of Deux Marble's room. Monsters will drop loot there, one of them is accessible only to a player who is finishing the dark eye quest, the other is inaccessible to anyone but hackers and GMs. If you can get to it, the Cursed Maze is also a pretty good hacking location. Killing monsters in Illipia's room works pretty well, since noone goes after it for any quests.
The Tomb is NOT a good place to hack. The first reason is that there are a lot of bots there, messing up your lures. The second reason is that the Tomb has always been a favorite place to catch hackers. The third reason is that the Tomb gets a lot of traffic, from people going to the Maze, amking a Screenshot more likely. Just because you haven't been caught before doesn't mean you will always get away.
