link site for sale:
http://www.cyberpornlinks.com
it has been around in its current form since 1998. I work on the site maybe 5 to 10 hours per week, it gets 3000+ people per day, has a decent amount of bookmarkers.
there are about 900 free sites listed, and it is mostly automated. a perl program creates the front page and link pages, and rotate the banners on the link pages every hour. Currently I use a database of 30 days worth of hosted galleries on the front page (the program stores a thumbnail and link for each gallery). the domain has 4470 links to it according to alta vista.
it used to have good google PR but in the past 6 months google has fucked me and I got pr0 for some reason for all my domains (I have about 50 adult domains, some were interlinking, I never spammed google, yes I emailed them nicely a bunch of times and even called a coule times). I used to get about 1000 google hits per day, now I get almost zero, the site also gets a few hundred yahoo hits per day.
asking price is 15K, which is about the current 6 months projected earnings, the site would be worth more if I could get the pr 6 or 7 ranking back. it would also be worth more if somebody spent more time updating it. I have not been doing porn full time lately so I am not motivated to maintain the site that well.
