To answer the last few questions:
1) The more you rate other people the more your profile gets exposed. This is why you should use a macro to do rating automatically and just run it for however long you want. This way your profile gets viewed more.
2) Also program a macro for the meet me function. Make it click yes. Then they will get a msg saying you have a half match if they have not clicked meet me on you, they will then be opted to view meet me profiles and click yes or no. Yours will be throw in randomly to see if they click yes or no to meet you. If they do click yes then you will be added to their matches list.
You really need to understand hot or not's system and the way the functions work to understand the above points. Hope it is clear.
3) You make money mostly when the geeks/pervs etc get you as a double match and your added to your list. Then when they explore further to perv over more pics in your profile they will also know that your on facebook so they will look you up - your profile is public and then they will add you and you accept. You can also make money via chat bots. But the facebook method has better conversion rates in my experience.
You can't really earn money from hot or not anymore as their filter systems are good. Use it as a way of gaining more facebook friends. Yes you can use they usually facebook adding methods but.....
As the leads/friends are from hot or not - plus the meet me function - you are targeting a well defined niche - the men want to meet you, their up for it as hot or not is known for pervs just browsing sexy pics to get off. This way you don't just have a facebook ewhore profile full of flaked leads - like people who just love to add and friend to say to people 'well i have 1000's of friends etc'
Then I use facebook methods (e.g - secret admirer method, ecard method, quiz method, house party method etc) and also lead them to external websites such as dating/sex websites, own personal websites, cpa gatways - if you ewhore you should understand this with out further detail.
Hope this is clear and you understand the method and reason behind it.
