I pulled this off USAsexguide concerning BP ads:
Be aware of the number 205-XXX-1687 do not text!
The above number is a SCAM. You'll get this respond- *ALERT* you listed on exposingjohns.com/ your number for soliciting a prostitute online. " If you did text already just ignore it. If you respond they will know that your number is a good number to harass you.
I have seen this number associated with more than one ad.
