72hrs ban due to garrisonbuddy?

Yesterday I got a 72hrs ban. Strange though, as I was monitoring the account 100% (while playing my main account) and didn't got a whisper nor GM messages. The account wasn't stuck and I was at the place where I've always farmed for greens with very very, VERY little population. So, I remembered to used GarrisonBuddy yesterday for the first time and about 2hrs later I got the ban. Is that just coincidence or do you guys think it's somehow related?

I basically never bot without monitoring it as I really do not want to lose my 2nd account. Therefore I only bot for about 2-5 hrs a day. Is it really the case that Blizzard will monitor your account after a 72hrs ban more frequently?

Ah: With my main and a third account (not the banned one) I also tried to multiboxing. As far as I know this is allowed and again, it might be just coincidence but is it possible that this is related?

Also, I have opened a ticket with Blizzard, saying that the only 3rd party software I've used is my multiboxing software and I really want them to unlock my account. Their answer was:

We have now reviewed the action and found that we have sufficent evidence and were correct to have suspended the account.

How can they detect that? As I thought Honorbuddy is not detectable? And the least I would expect if one person (not a program) is banning me is having proof?

Cheers
