At first glance expertbee.com is just another q&a site.
However, they are asking their users to pay for answers, and then not delivering the answers.
Sometimes a user will pay more than $100.00 (US Dollars) for an answer, and then get scammed.
Since PayPal's policies prohibit the dispute of a transaction involving intangible goods, scammed users are helpless.
I haven't seen expertbee documents on scam.com yet so I am just letting you know.
