@peeps920,
1099's don't require a signature. The only thing that requires a signature is the form transmitting the batch of 1099's to the IRS.
There is something odd going on. People don't usually try to generate a fake 1099 for themselves unless they are trying to hide an income source and justify their increased spending spree from the IRS.
If it were me, I'd go to the former friend and ask them directly if what you heard was true. I'd also ask to see a copy of any paperwork that was submitted. Depending upon how pissed off I was, I'd also make a call to the IRS anonymous tip line for whistle blowers.
