PM abuse can be controlled by you the user. All you need do is this:
1. Click on profile from the menu tabs above
2. On left-hand side, under modify profile, look for personal message options and click on it
3. On ignorelist, add the person's name that you wish to ignore PMs from, and click on change profile button.
*poof* PM annoyance gone. I strongly recommend these steps to anyone receiving abusive PMs.
