Do you use addresses's that exist local to you or just address's you know you can access?
How do you go about choosing the names you use?
Depends if course on whether you are making your own accounts, or buying one from the marketplace on here where all the angst is taken out of the equation for you. Since Christmas when the much stronger ID verification procedures came in with PayPal it has not been advisable to create accounts ourselves, another bonus to buying one on here is that we can get the verification paperwork that was used in building the accounts and we then have it to use to raise the £1900 EU limit, all things to keep in mind with new accounts however they are made.
Another thing that seems to be system wide (with E5ay and other companies) is a way to see if an address even exists... 123 Main Street, for example, might not exist as an actual mailing address in zipcode 90210. I've noticed a lot of forms no longer let me fill in just random stuff for an address, even if the city and zipcode match.
