So complicated was the fall
I got a very interesting opinion why someone like me was banned. Blizzard might have used any automate check for 11 boosters running TW dungeons. One of them was Blood Furnace, which i was running in usual tbc mode with my high level character. As blizzard decided that 11 booster xpoff bug is a bad thing they might have created algorith to check the speed of finishing dungeon because 11 levels clear them very fast. I also was clearing fast because my lock had 228% movement speed and i spent like 1:20 min total running from the start of dungeon to the bosskill moment (after clearing it with my 70 character for like 2 min). This might have lead to the situation where due to speed of the clear i was triggered by their system as 11 xpoff booster.
