They can do whatever they want. It's their site.

its just that Ive never seen that happen before xD

It depends if you were hacking or not. But yeah they can do that

Yea I've had it happen before, they took away my gold too.

Of course they can do that. Everything on that site is their property - including your account.

Yes they can do that.
Its not like its your site
And they would have probrably sent you a pm like this:
Subject: [GAIA] Your inventory has been modified.
Body:
