People being hacked since the last Server Check.

I'm concerned for the fact that the hacker(s) may come back onto the account to check it again (and hack it again) - has anyone had/heard
such a case?

Doubtfully you'll be hacked twice by the same hackers.

Why would they bother checking already hacked accounts that are either abandoned or still recovering the lost meso? They might be very lucky and find out that the guy they hacked two weeks ago is a godlike scammer merchant and made 2b meso with those 100k the hackers kindly left last time, but that's rare.
