Yeah i never use my real name just to be on the safe side. Just make sure you can sign the fake name reasonably well and that you don't sign your real one by accident.
side note: if you use a CC online western union....all amounts require real name and ID since you must have your real name and phone # and credit card #....and they do check that out. they called my ass on my home phone to make sure it was me to authorize my first CC western union online payment. after that i just do it without that hassle. but they check that out. just to let everyone know who intends on using online western union (credit card only).
I know of a bro who got busted by using WU. He didn't get popped but they wanted him to help out with their case. Nothing beats cash. WU is like leaving a witness at a murder scene.
