You've got nothing to lose by sending in 'appropriate' docs because if you don't the accounts are dead anyway.
As for the p/p accounts these may well be taken down in due course. They can still be used for purposes other than e/b but that would be up to you how you could possibly use them. They can never be linked to another e/b account.
TBH I still think it is very remote that it was the address in itself that got the accounts taken down.
You need to fully review how you set these accounts up, how you formatted the addresses, everything before you make any more new accounts.
I use nothing but virtual addresses, both local and national companies and have never had an issue.
Using box numbers on personal accounts is a big no imo, these are really best suited for business accounts.
Everything about the account information should appear genuine to the eyes of e/b and p/p. Anything that would not appear 'normal' will undoubtedly raise flags.
Good luck with future endeavours.
