Same caller (This is Corey ... id-theft scam) see: http://whocallsme.com/Phone-Number.aspx/818-870-5077 http://whocalled.us/lookup/978-570-2361 http://800notes.com/Phone.aspx/1-818-870-8183
Caller-ID is forged (at least the name, and probably the number, too) Most recent call (2008-05-26) claimed to be "MCCAIN 2008", but that's one of a dozen or more -- all different -- this week. Calls cellphone, calls home, calls office ... Where's the FCC when you need them?
morgandrexen.com and clandarkstar.com (mentioned above) are both registered anonymously via "proxy"s see: http://open-whois.org/lookup.cgi?domain=clandarkstar.com&record=2007-01-24%2014:25:08 for example, hosted on Lunarpages, whereas morgandrexen.com is hosted on another popular scam-hosting place Time-Warner Telecom.
There is no (current) reason to disbelieve that this is, indeed, Liberty Managment / Broadcom actually doing the calls.
