There are eight different accounts in this thread "congratulating the launch" with their first comment. Half were created six hours ago right when this was posted.
My first thought when I saw your post pointing out the congratulations comments was one of the ending scenes from Neon Genesis Evangelion where they say congratulations repeatedly.
I posted true, verifiable information about this thread (that a lot of people voted up). I didn't accuse anyone of anything, people are smart, they can make up their own minds.
This isn't some complicated thing, there's a site guideline specifically about it and you should try to stick to it like everyone else because it trashes the forum.
You can just mail this stuff in.

Regardless, this is very spammy marketing.
