Hi Frank,
if you received a questionable response after you inquired about any listing on Anamera, please forward the email to us, but be certain to include the listings "Ref. No." from the car's detail page, or at least the detail's page "URL" (the web address from your browsers address bar).
This way we can remove that specific listing.
Unfortunately, these schemes extend across all different industries/markets and sites (not just cars, not just transportation, and not just Anamera). In fact the same stolen identity is used widely across the Internet.
These schemes rely on the free "throw-away" email accounts that all the big email providers love to offer. And, of course, the Internet connections are usually disguised by bouncing off anonymous proxy services, and/or hi-jacked PCs of millions of people who don't install security fixes to their operating system, web browsers, Flash, Acrobat, and other applications every month and don't run virus scanners.
As a result there is no common "source" that can be blocked.
The key is that one should never trust any information or documents over the Internet. Extra caution is warranted if people use free email accounts to contact you. If they are a legitimate Internet user, they'll likely have a business email address, or an official email address from their Internet access provider - that is tied to an actual account and "brick and mortar" address.
Furthermore, it's very easy to set up fancy looking "escrow" or "freight services" web sites, and to fabricate any kind of "shipping" documents. Don't assume it's real just because it looks impressive! Unless you touched the car with your OWN hands - don't pay a dime. If everyone were to follow that most basic and common sense rule, all these schemes would cease to exist.
(Then again, I never understood why it was called "common" sense, when it appears to be so UNcommon.
