In the area where I hobby. A backpage provider who was some what popular was arrested, by the police in july.  I have an article which has the provider's mug shot, and gov name. On tuesday the police started using this porviders pictures, stating she was a california girl, However the contact number is a cell-phone number based out of the city of which this police department is located.

I know the hotel they are doing these stings at. I'm not sure if she's been flipped, or if it's a policewoman on the proof. I'm not speculating, because I more then enough proof to prove this.

I tried posting a warning on the local bored but it was denied.
should I post a warning on the backpage city the postings are done in.

If you posted exactly what you did here, it should be fine but based upon what little I can see of those failed posts, it looks like you tried to include some identifying marks.  While I personally understand your desire to protect your fellow man, there is a line that can't be crossed when it comes to outing others.  As I said, I can't see exactly what you tried posting, but I'm guessing you crossed that line.

If your post had personal information of a hobbyist and or provider we have been instructed by admin to deny the post. Just think for a minute if had been you caught up in the sting would you want your personal information plastered all over the place. Yes it is public information when it hits the news papers but as hobbyist and providers we have all gone to a lot of trouble to remain as anonymous as we can. That is something we will respect here.
If you can find a way to post the information without links that provide personal information then it will be approved. It is not a problem to instruct folks where to find the info just don't link to it form TER.

I believe the OP probably has sufficient evidence to out this girl, and warn the community, BUT, it's remotely possible that she is innocent, and thus needs protection. TER (rightfully IMO ) does NOT allow OUTTING anyone (male or female) on public boards.  What you CAN DO  (although your inbox will be overwhelmed) is post for guys to PM you for the info on your local board, or whatever board this girl is working in. You CAN out her in PMs or email.  It's the rules, and I agree with them.

Sometimes guys want to post about girls & STDs.  For obvious reasons, TER doesn't allow those posts either.

to post an article that has someones personal residence in it.  No one here that I know needs that information for any reason.
This in itself is reason enough for vip membership and best handled behind the scenes.

If they committed those resources to feeding the hungry and shit like that, maybe the economy wouldn't have been so shitty. Just a thought.

Believe it or not,  I have spent $8 for an ad that repeated 4X on BP to warn of a scam.
A sting is serious and other guys should know.
