I dont know if people here are intresting in this. But i can if people are intresting make 2 huge thread.
One from a system what i use and where you can earn good money, legal. But that thread is huge, so there is many to tell about it. However that thread is including a referal link, simply because that sire require that by registing, without that its not possible to register.
The other one will be a collection of best monetizing ways with many systems and some small info about those sites.
If people like this all i can post this all.
