Yes, it is true. I’ve been scammed. Sort of.
The other day I listed for online sale some computer equipment I had laying around, and this was bound to attract scammers. I don’t know why, but it happens, and it turns out almost always these guys are from Nigeria. It could be that laws there are not very strict with these matters, or that it is a traditional way to make ends meet in a tough situation. But it’s no wonder most eBay auctions specifically forbid Nigerian bids.

As I was saying, I received several fishy offers. Note that I’m posting the scammer’s private information on purpose :)

It’s astonishing how many guys fall for it. I guess the phone is a VoIP UK number, but hey, guess what?
This friendly guy that is “now in united kindom for a purpose” is writing from Lagos, Nigeria! GeoIP sure is a nice thing. Which by the way is supported in Cherokee, in case you’re wondering how to use that on a web server. Pretty handy.
