No, Gumsel, you should keep posting. The net is a big place; you can`t be expected to know who everyone is or the circumstances behind their postings. The only thing to do is remove pics as they are requested. The burden is on the 'owners' of the pics, not you.
note: This sort of thing seems to pop up regularly on this and other sites, so my advice to people who post their own pics is to be sure they really want others to see their stuff, because they WILL be re-posted and they WILL get out of your control.
Go to any link site (amateurcurves, dailybasis, fantasticnudes, etc... there`s literally hundreds of them) and you`ll find amateur links that have pics from this forum on them. In the past few days I`ve seen Oxy`s girl, Special K, Jinx, and many others on these sites. It`s out of your control the second you post them. The simple truth is that the internet is the absolute worst place to put anything personal, so use your head.
