This is the first time I had to report a pirate

You should be able to send in reports on the site. More than just "report misbehaving players" but one where you can actually say, "Bob McPants Level 34 in the guild Pants Rule was doing inappropriate actions to my character bla bla bla" and then you could attach some screenshots, or even a video. They locate the person, find his account, and terminate/ban it. Simple as that.
