I found a funny Get Paid to blog program last night. It is called Creamaid and you can see an example in my last Orlando post.
The only way you can join this program is when click on another blog with the Creamaid widget and then you take the same task.
The pay is not that great so far I only found program that are paying $1 and an extra $1 for referral.
As soon as someone has used your widget you should get an email that gives you a code to get paid. This program is still in the Beta test but it can be a nice program if they get more advertisers.
If you want to write or advertise about adult sites they have no problem with that you can see on this post on Thailand bondage blog.
