The dev is from Europe..
Now it's like 4AM. You expect people to be online at 4AM? Just wait until morning and see what happens then.
If it's a "scam" then screw it.
That's a fair comment, however...
The coin was launched and there haven't been any further comments by the devs, not even when it was 9pm in europe.
If I was launching a coin I would want to be a part of its launch and at least be active in the forum for the first couple of hours.
By the way I'm in the UK and it's 3am here.
