Hmm, its always possible that you got reported using bgbuddy and it took a week or two for them to do the investigation.
Multi-zone profile is good, but if you do bot again I'd recommend making a couple of private profiles as well and mixing them up.
I agree with bjsaust, atm it looks like a best solution, multi-zone profile with random fly-around path notspecific to any nodes and preferably to make dublicates with changed routes and switch every hour or so just in case.
