The only harassment he suffers is in his attempts to trick and defraud people. Quit trying to scam people.
I have seen the old thread of this project before.
And the reason why it was abandoned because of his shady profile.
And I would say, this will never go somewhere.
The "dev" should stop trying as I can't see any promising progress here.
Even without those so-called critics, I doubt he can actually deliver.
