Those were all the warning signs. I was unable to understand the business model behind this project. That's what raised my suspicions.
Do all this work, maintain all this work, pay for server space, all for "nothing". No ads, no way or being compensated.So it appeared to be the only way for this to be profitable, was a skimming scam.
No evil intended. It's just a project.

Good luck with your project. In future, to be less suspicious though, do put up ads or some other cross promotion so it makes more sense for someone trying to understand your motives.
By the way, calling a project sounds like a "temporary venture". What happens with all the remaining coins when you decide to shut down the project?
