Something to watch out for are directories that appear to have a number of well known ladies advertising on them so you think that must be a good site so you sign up for paid advertising.
My profile details and photographs have been lifted and put on such sites as naughtyreviews.com and I have never asked to be on the site and I would certainly never pay for advertising on that site.
I use Punternet, Adultwork, UKbelles, OAG, Backpage, Punterlink and list of some of the freebies directories. I also use Twitter and Facebook.
I can't seem to register at Puntingzone
