Can anybody please help me how you can earn money from Review Stream

I cannot see how one becomes a member apart from starting to write reviews. The FAQ answers some questions but has nothing about membership. There are a number of things that make me seriously believe that this site is a scam. 1) Ownership and address of the owner of the domain name are intentionally hidden with a subscription to a cloaking service. 2) There is nowhere any information about the Head Office or physical location of the business. The contact address is a Yahoo generic account. 3) The offer of $2 per review seems generous, especially considering that they are not very picky about length and quality. One can reasonably assume that most reviews are actually paid at the bulk rate. 4) The FAQ is written in rather 'unEnglish' English and has many grammatical and spelling errors. They do not specify anywhere what are their 'criteria' for accepting reviews. It doesn't seem that their standards are very high.
