If you want to create a second identity for mongering verification (only) you can get very high quality fake ID's on line, my under 21 yo son has several that he uses to get into bars and they scan at the bars. That being said, I always try to follow the sage advice of the great Genius and only commit one crime at a time. Possessing/using a fake ID can get you in a bunch of trouble.
I'm also a bit put off by the verification, they want my real name, address, etc, but aren't giving me theirs. I understand safety, but that's a 2 way street, mongers can be robbed on site, and blackmailed, particularly if the verification reveals you have a high income job, are a high value person.
I've done verification once or twice, once was for a porn star so I wasn't worried. The other time I sent a photo that was publicly available online so I could claim someone else used it and deny it was me.
There are also a couple pay verification sites out there, I'm a bit leary about using if their records and servers are ever seized
