AdultStream.com was registered back in 2012 and expired at Dynadot. For some reason this auction closed at $381,000.
This is not a backlinks play as Ahrefs shows 0, same for Domain Authority. It looks like the name was parked at DAN.com. According to DotDB.com AdultStream is registered in 7 extensions.
It will be interesting to see if this gets paid. If it does I might raise the price on CelebStream.com.
