This is the greatest of opportunities to mess with the IRS. NOW DON'T actually do this, but this is how it would go down.
someone writes a program (spreadsheet, whatever) and prints huge number of bogus ones of these. Of course they would be from a bogus company. Maybe from a company or organization they didn't like. And mail them to the IRS. Now at the IRS "intake" centers, they'll open and start processing them (entering them in the computer). Then when they try to reconcile them, they won't match. Oh the havoc this would cause on the IRS and companies "named" in the 1099s.
Again, don't do this, it's just a theory how someone else might mess with the system. I'm just saying.
