cybersquatters and "limbo" situation
I have around 25 domains still up the creek because of this fiasco.
It's not just cybersquatters that put those worthless search portal pages up - eNom (which RegisterFly was reselling, and with whom some of my domains are still listed) grabs anything which expires and changes the DNS, but leaves the registrant information untouched, so it looks like I'm the fool with the frigging search portal!
More recently, I've had domains grabbed by ZusCom, some bunch in London, with apparently no plans to auction / sell the domains, they presumably plan something else (eg building collections of links to give high page ranks for selected domains, perhaps), but in the meantime, they have their own blasted search portal page showing "This page is parked free, courtesy of Cheapnames.com" (ZusCom is a GoDaddy reseller, and Cheapnames.com is their own domain... .info domains are being sold cheap at present - .info costs US$ 1.22)
