Even now I can't access the site have they disappeared during that time?
The site works fine, just the link to the whitepaper returns a 404 but I have no clue if that hasn't gone well before.
Contrary to what some say, it actually makes no sense for them to take down the website, why should they?
They most likely have already lots of VPS accounts, just park it on one of them and wait, even if they manage to fool a single guy for 1ETH is still a profit for them, in some countries that's equivalent of one month of hard work. Most of them are just going to leave that on till the domain expire and by that time they would be up and running a dozen more scams.
A roadmap like this reflects that the project does not have a clear vision, mission and work program.
I would say that it's better to stay away from any project with a roadmap covering a lengthy period of time and especially one mentioning the dates.
Look how hard is for ETH to keep up with the timetable, but a small project already knowing when they will do certain stuff in two years time?
That's bs and we all know it is almost impossible to keep those promises.
