Blizzard Entertainment has had quite a bit of activity lately on the domain front. Earlier this month the company filed a complaint against the owner of HeroesofWarcraft.com. Then this week, Blizzard registered the name ProjectBlackstone.com (WHOIS). ProjectBlackstone.com was at one time registered to a resident of Texas, but expired in early 2011 and wasn’t renewed by its original owner. On November 26, 2012, Blizzard registered the name.
