That happened because this campaign started (and probably ended) more than a year ago, just some idiot bumped it and a bunch of his colleagues followed him (posting crap without even reading the thread).
Many sites fail to succeed and it is not that unusual that sites are down within a year of their launch (or maybe this is temporary, but my point is that the campaign is apparently not active nor should be this thread).
I already reported this to the mods, but they probably have more important things to do that controlling spam-posters.
But suddenly one of there team login with new account and paid many user you can see it then again disappear
