Scared me for a minute... Probably patched today anyway.

says who? or what are you referring?

this. they probably won't ban for the AH clock, but if they view it as an exploit(it technically is, you're messing with the way the AH works) you'll probably get BANNED.

I remember when blizzard banned bots and accounts and all that kind of stuff in d2 and WoW before...

Then the bots just kept coming back and prices continued to drop and everyone thinking that prices will stay the same or go up felt retarded.

False, it would be considered an exploit and first time offence is a verbal warning.

I won't debate anything with you because your sig is auto-win. We'll just have to wait and see how many people get hit by the BANHAMMER.

Stop speculating and read the facts straight from Blizzard.

Verbal warning or temp ban (likely 24hours to 1 week tops)

EXTREME cases get banned.

Cancelling an auction does not direct affect others and it's affect to others is virtually nil.

If someone gets temp banned for it, it's because they've done it hundreds and hundreds of times a day.

Yep.

Same thing with scamming for in game items, you can complain about someone swapping gear before you hit accept, making you drop on the ground etc. and guess what?
Their policy on scamming is that they will do nothing about it.

It appears you are "arguing" with the wind.
