Nobody said it's a scam, the site Admin is immature and lacks basic communication skills, oh and coding for the site is worst of all faucets! Untested!
The criticism about the current flaws and bugs is justified, but in the end its a free service (if you have not desposit anything), also we don´t know how many developers are working at this project. I am pretty sure most of us could not handle this much responsibility for such a big project and we can´t see most of the code. So you can´t really evaluate the quality of the code.
Not a free service, Admins earns thru fees + ads revenue, and users spends lots of time on this site, Not a big project too, this is just greedy owner mismanaging the site.
