The site "8chan.co" is never coming back.
Once a domain is hijacked, it is next to impossible to recover it. The squatter/troll will hold on it, change registrars, and Hotwheels be unable to recover it. Then the new owner will flip it for a profit most likely.
HW may start another site, maybe with all the same stuff, on a new domain, but that's the best he'll be able to do.
And with all this downtime, and with this big shutdown, all the momentum 8chan had is gone.
It's ogre, anon.
