I've come across a few shares of this service before, but I didn't send any money here because it didn't really interest me. On the other hand, if such a service is not a quality service, I do not send money because it is likely to be scam. It was a nice information headline that you created with your evidence, thank you.
Yes and me too, it might be lucky before my decision to deposit, I took time to mess around with these basic security features such as change email address, change password, remember password on the browser.
A critical flaw found on change of email address which it require only your "new" email address to confirm the change which it can cause a serious issue of being hacked without any notification (in which the correct way it should send confirmation link to the old email address) to make the account owner aware of.
A second flaw (not really a flaw but UI/ user awareness) relating to color of the icons on the login box which can cause people with difficulties in recognize colors or using a monitor with high constrast to make mistake on switching login mode (username/email). This is where I got locked out and did give some angry words.
Before going to bed, I did think of few suggestions which make it better (and after a calm) but thing went wild, my chat messages deleted and my ID blocked from rejoin their group...
