I don't think mismatched names between PP and a bank is a common problem (currently), but I doubt that using your own name on PP/Ebay will link your stealth accounts to your suspended account.
How could PP possibly stop and look closely at every "John Smith," or "Michael Miller,"
or "Jim Johnson," or "Joe Williams?"
They'd waste most of their time chasing waterfalls.
If they checked every matching First/Last name on Ebay,
less than 1% of users would be Stealth Ninja Ebay Users.
On the other hand, if they are already looking closely and suspiciously at your stealth account, and have several other links, then I guess they would deem your stealth account suspect.
I just typed my own name into facebook,
and I can see dozens and dozens of my name. I can even see several with my First, Middle, and Last name (not that the middle name would be an issue).
Just now found an interesting website,
How Many of Me.
There are over 45,000 people in the US alone named John Smith.
Type in your own name to discover that you are not a unique snowflake
(for the record, it is a myth that each snowflake is unique).
If you discover that there are only a few hundred people in your country with your name, then if you're concerned about mismatched names between your bank accounts and your PP account, you can legally change your name to John Smith for a hundred bucks.
Then you won't have to worry about using nicknames, or mismatched names with transfers between PP and your bank.
