as you well know a lot of folks are getting this message when they try to post links but if you go to almost any big fanpage you will see these ewhore spammers with a really big fake pic that seem to get around it consistently. I have used a PVA and copied it exactly but won't post, so there is a solution. Also used new IP and still facebook won't allow me to post the link. My guess is that it's the user agent. If you feed a special useragent to facebook it will let you post any link.
