People being hacked since the last Server Check.

Do any of you have this encounter? Today I was told that I would get hacked because I looted this guys Mesos bag or something. After I looted he started laughing and telling me he was going to hack my stuff. Anything related to that? Just curious so I can take precaution.

I'm not sure if you're being serious o.o
If you are, don't you think that's a little too dumb?
