How likely to get a ban?

After the second or third time you get reported your accounts would be flagged as a multiboxer and all we would do was check that all accounts were in the one name. If so, just disregard the ticket and put it down as solved without even looking.

For real you checked the names? I have been multiboxing on battlenet with different names from tbc to mop and 300k HKs worth of reports (however that number translates in reports) and nothing ever happend xD. I either got lucky or german GM's didnt take it that serious with the rules.
