I agree with you when you say to new user should stop been lazy and carry out the own due diligence - however even if you carry out due diligence and have additional verification reports done at the end of the day your checks may come back positive but once the company get your money you are at a loss as you have no power over them.
I have bought goods from a company which passed all my checks and other checks performed by reps but still once they got my money after some time I found out the my goods where mostly not to come.
Initially I invested in a sample order worth 1/5 of the real value and this came through but on my later order none of it was sent and to do this day I have nothing.
What I am saying is it easy to get a trust pass and gold membership and it cost even less to setup a official registered company. Once you got this the scammers company will mostly pass all due diligence.
How much does it cost to get a gold and trust membership?
Will alibaba aid in recovering the money? Do they compensate? I think the answer will not be in my favor!!
