How can I earn money online but still avoid the scams?

i honestly think there are alot more people on the internet who lie about earning heaps of money in order to get yours. I think some good tips to keep in mind. make sure the website isn't brand new has been running for awhile and you have actually spoken to other members who have recived payment either in a chat room or your refferer etc. I like to stick to site that i have been reffered to by friends, or have a good reputation on independant internet forums, reviews. There is opportunity out there but you wont get rich over night there are however many sites that can earn you dollars out there.
