Seriously, I hope you get your stuff back.

99% of the time, you've either shared your login info in some manner or you've used an easily guessable password. People who know something about you, like your favorite band, favorite food, partner's name, etc., are also very likely to be able to guess your password if it has anything to do with any of these.

There are legit hacker tools that can brute force you down if the attacker knows your login, but your account would show (at minimum) hundreds of login fails in a short time. You could also have a keylogger, but I think your bank account would be a sweeter target that your imaginary stuff in a p99 account.

In all, it's really, extremely, unlikely that you got 'hacked' in the sense of someone with mysterious powers just randomly cracking into accounts on a 15 yr old elf sim, as people like to call it.
