And you post will be a big mouth only if you cant provide any proofs of your accusation.
This is not how to accuse a site as a scam, you need to provide valid proof(s). Otherwise, it is just a baseless accusation to make the site looks bad.
Frankly speaking, I have no experience with this site and I have no ideas whether this site is legit or not but I cant see any valid scam accusation against this site.
So kindly prove what you say if the site is real scam as it will help others to avoid them.
