Buyer Trust:
Buyer has 10 ratings. And buyer only placed one bid as a service provider which pretty much not makes him a SP himself.
I guess we can trust the buyer.
Conclusion:
Buyer mentioned few requirements. The job is to write 15 FAQs. Buyer mentioned that he/she wants the writer to study his/her site and answer the questions that are asked by the visitors.
I actually have not understood this and I think anyone who wants to do this work, should clarify things using PM.
Buyer has not mentioned the rate: so it looks like the pay will be decent. New comers and old members both can place their bids on this project.
NOTE: I am not saying anything bad about the buyers. I am not saying that any buyer is a scam. The reason why I may say that a project is unacceptable: is just my own thought based on my freelancing experience
