Up until recently, I worked at a Chamber of Commerce where we received calls from all around the country, asking us about the legitimacy of verifiable scams.

I worked very closely with both our local police station as well as the Federal Inspectors with the US Postal Service. The local police were especially concerned with email scams.

If you want to go to Spain, do it - just not to meet people who either want to hurt you or rip you off. It might sound cheesy, but talk to your "local authorities" about this; that's what they're there for.
