In my opinion, the fraud and scams tags should not be combined.
A "scam" is when an individual is tricked into doing something that causes him to lose money.
"Fraud" is deception by misrepresentation. It is the broader term.
When someone obtains my credit card number (perhaps through hacking or skimming) and makes a charge, I have not been scammed. I have not been tricked, and I had no participation in the matter. But the thief has committed fraud by misrepresenting himself as me and making a fraudulent charge to my account.
We often get questions about scams. Some present a scenario and ask if it is a scam, and others are asking for the details on how a particular scam works. In any case, what makes a scam a scam is that the scam artist tricks the victim into participating in his own loss. These should all be tagged scams.
Questions that ask about fraudulent bank transactions should not be tagged scams. A few recent examples:
None of these should be tagged scams.
These "fraud" questions could arguably be tagged identity-theft. If we're going to clarify the fraud and scams tags, we should probably look at the identity-theft tag as well.
Here are some proposals for tag excerpts, to get discussion started:
scams: Questions about identification, prevention, and resolution of scams. A scam is a type of theft where the victim is tricked into being a participant.
identity-theft: Questions about identity theft prevention and recovery. Identity theft occurs when a thief steals personal information and uses it to impersonate the victim in financial transactions.
fraud: Questions about fraud, which is a deliberate deception used for unlawful gain. For questions about "scams" or "identity-theft", use those tags instead.
