I've been with 2Hot4FB since mid-October, and since then they have rolled out new functionalities and great ways to make passive income. You can directly share from the site by clicking any or all of the six share buttons, or copy/paste the direct link to share on your website or wherever. Previously, I wouldn't share pictures of this nature because there was no way of making money from views. Now I tweet them left and right because followers don't have to pay so they click away!
Now they added a pie chart representing your total traffic, with each slice showing you where your traffic is coming from. I have no idea how 4% of my traffic comes from Bing, or how my traffic comes from sites I've never even heard of, but that's the beauty of this site. Throw the links out there, and they'll circulate the interwebs with the views resulting in paying cash for you!
Support has always been quick to mention tips or when I've made a mistake. When I first joined, I misunderstood one rule and had my first couple of pictures removed and an email stating why. Support was quick to explain via email and live Twitter PM's, and after that I was on my way to making easy bucks from all the nudie modeling pictures I have laying around.
The site also allows you to share 5 links to personal sites, clip sites, cam sites, wishlists, or (like I do) to a texting service you provide. *and* it tracks how many times each link has been clicked, which easily verifies that this is a fantastic way to get paid for sharing nudies AND directing traffic to your other forms of income.
Speaking of traffic, I love that they feature 10 girls each day on the main page, meaning I don't need to rely on my own (lack of) twitter followers for views. I've been featured many times just by uploading fresh pictures. I bet any model with a larger Twitter/Tumblr/FB etc following than me would clean up nicely.
Try it out, it's definitely worth it:
