Yes, it's yet another ICO scam (why do people keep falling for this shit anyway).
The scammer disappeared with almost no traces left, right after the goal of 40 BTC was reached.
The pre ann thread was closed and
the XLTH website was taken down.
If you can help in any way to hunt down this criminal, you're welcome to post here or contact me.
And please no accusations without hard facts. I am taking this one very serious.
Another thread that is being used for this purpose is
this one by Jimmy Recard btw.
Let's use this for the factual stuff, not for the wild accusations just based on gut feelings.
I think the hack into the devs own account at his ICO and XLTH-Wallet accounts is a good starting point.
Please, let's just post hints and allegations that you were able to verify up to a certain level of certainty. There are more scams and more scammers on the forum, but they are not necessarily pulled by the same scammer just because yout gut feeling tells you so.
