How to proof opportunities in a simple way?

[imported_Richard_W]

I have seen many say they are offering great opportunities here in this forum.

I have try out some offer based on the ad, its quite spent time to know wether the one will works or not.

Do you know how to proof opportunities in a simple way?

P.s : Please be noticed that I mean to proof (not to review or just check)

Are you wanting a way to know whether an opportunity is legitimate? I just want to make sure I understand what it is you want to know.

you can never proof anything without giving it a shot..
of course, those too good to be true got to be spam..
