Why bother? There are literally thousands of these going out every day (I get one almost every other week), and the authorities are far too busy to pay much attention to this. Especially when that iffy part about “find and catch them” is so unlikely.
Locally, bank tellers are becoming used to this, enough that they will stop customers from depositing such checks in their account. They ask the customer if they are sure this check is legitimate and not a forgery, and point out that they will be charged fees by the bank if it turns out to be a forgery.
The tellers are especially careful to warn them when the customer says ‘I want to deposit this check for $5,500 and then get a cashiers check for $2,995’ – tellers can recognize this scam.
Surprisingly enough, some customers get angry with the teller who tells them this. As if it was the teller preventing them from getting the thousands of dollars that came in the mail! Some people are not only gullible, but stubbornly insistent on being gullible.
