Credit Card # stolen twice in 6 months!!

My credit card number has been stolen twice in 6 months. The questions I ask myself: is it retail employees stealing numbers, is it online companies being compromised or acting as perpetrators, how many data-bases have been hacked? My question to you is: has it happened to you? If the criminals are local, can we find the source?

Maybe these questions and this conversation can lead into a fair and actionable discussion of VS crime.
