Search Engine Optimization scam...they make false promises that your website will be listed on the first page of Google searches, that of course is not possible.
I answer the calls anyway just to waste their time.
No idea who it is. They call, repeatedly, and they say nothing.
Caller id says, "Culver City, CA"
I can guess what it may be, but cannot say, for sure.
*Last time I answered with, "what now, retard?"
Yeah, then I HUNG UP, or a change.
