Safe to put up shop?

Supposedly there is (or was) a glitch related to the double-login problem that allowed abusers to dupe their mesos and/or items. I have no idea how widespread abuse of this was (or is). Last time there was a major meso dupe event, Nexon deleted all or most of the mesos from shopkeepers who happened to sell so much as an ore to someone with glitched mesos. So is there a risk of them doing the same trick again? Should we not put up any shops from our main accounts for a week or two?
