As mentioned reddit and twitter works like a charm for porn sites..
I created a script to auto-retweet and favorite specific #hashtag and keywords mentioned by users ( without links - this is the trick ) - if you retweet or favorite a tweet with a link on it - most of them are spam bots. Instead, without link - 99% are from normal users - so you get noticed easily and high chance of converting them ( if you're running a pay site ).
Example - This method highly recommend if you're running a pay site or adult toys ecommere store.
find the keywords and specific hashtags - target the tweets without link.
