I built a kind of adult blog and have had problems to raise traffic for it. Most sites related to that topic, say adult forums/communities, are reluctant to link to different sites (unless you pay for that)... they simply ignore your requests or treat you as a spammer when trying to post or comment using links in your signature, avatar, and the comments themselves.
I have also used some kind of unethical spamming such as trying to promote the site in adult chats, and e-mails, but no luck of course.
Can you offer me some kind of orientation in this regard?. It seems that with adult sites the strategies need to be different than those used for regular sites.
I don't pretend to invest money for advertising, will there be any free technique?
