Yes, that's what I'm working on now. As you might already know / have guessed, gambling is not a really well regarded source of enterntainment amongst... well, amongst 90% of the world popppulitaion, yet there is a huge market for both online casinos and affiliate sites. I believe it to be the second biggest internet market after porn, so, yes, we live in a weird world.
Honest linkbuilding is almost impossible, there's really few people that would dare to post an entry on their reputated blog of the "check this out, my friend's new casino site" kind, neither placing on their site a nicely anchored back-link.
We also do CMS web-development, but, of course, not a single client has accepted to keep a link to our casino site in their footer.
We have tried some link-baiting technics with interesting content by sending it to news aggregators, but most of the feedback we get (after the users read our url) is of the: "gonna downvote the h*** out of you lousy spammer!" kind.
Our site doesn't look dodgy at all, we intended to get rid of the sordid look that most affiliate sites sport, and I think that we succeded. (Here it is, if you guys wanna take a look http://www.ilovecasino.es/ ).
So here we are, out in the cold, developing our own "satellite sites", working hard in the seo for all of our other sites, giving away free drupal templates that carry an uncloacked link to us in the footer... all the classics.
So, any nice feedback on how to get sweet white-hat links in such a complicated market will be strongly appreciated.
Hope you can pardon both my rather long question and pretty poor english
