After looking at recent "edits" by Gay Guy all it showed was vandalism and just destroying the site. How should we report users like this. I don't think posting to meta every time is appropriate but I had to ask.
Report it as spam (or reject suggested edits as vandalism) and move on.
A mod or a cadre of 20kers will be along presently to delete the content.
If it's repeated by a user and they haven't been dealt with for whatever reason, flag one of their posts with a custom explanation and point out the pattern. In addition, or otherwise, do as Raven says.
