Hi!
As this is just a vague idea, you are free to flame and do other bad things :-)
What you need:
- A set-up (And disguised, as you don't want to get banned :/ ) Cheat Engine with the actual code for Mountain Climbing
- A priest on about the same level of the person you wish to ban
- The player you wish to ban has to be standing near a wall with a slight slope
We all know, Warden checks for the player's offset - If you modifiy it with CheatEngine or any other Mountainclimber, it will ban you almost instantly as soon as you try to climb a wall.
What you have to do:
1. Log in
2. Find a safe place, so the player you want to ban can't fear you up any slope, hill or buidling
3. Duel the player
4. alt+f4 out
5. Start CheatEngine
6. Log back in
7. Mind Control your "enemy" up a hill (You see, if you mindcontrol a player, you can actually move him whereever you want ) , to attract warden's attention on that player.
8. Tadaa- banned. Now just alt+f4 out, close warden, log back in and be happy.
--------------------------------------------------
As I already mentioned - I can't really test if it works, because silly me used aspeeder and got banned instantly.
As far as I remember warden only bans you as soon as you actually climb a mountain, and not for changing the value. Of course blizzard might have changed it, so that you get banned as soon as you change the memory value.
I already mentioned - I don't know if it works. But I just got this idea and felt that I had to post it.
Maybe sum1 can check on it? (Please watch out, might ban you maybe...)
