I have been on this site off and on for 10 years +/-, and I can't remember a single time that I've felt the need to report a profile for anything.
I can't begin to tell the OP how much I appreciate them for being bold enough to come out here on the forums and identify themselves as being the sort who regularly go though profiles to determine if they should be harassed a bit.
I am pleased to say that within about 30 seconds I'll have three profiles permanently removed from the OP's list of things to investigate.
I find this behavior to be petty, immature, and a very clear indicator about the person(s) involved in it.
