The only people who verify to Theymos are people that hold funds for the forum.
I don't think this is true. Back when John K. was having
escrow problems (there was a several month delay in him releasing funds he was holding in escrow), no one seemed to know with 100% certainty what John K's identity is, and BadBear posted that theymos has not asked for his identity:
I wouldn't get your hopes up, I doubt theymos knows much more about John's details than anyone else. I've had the same opportunities as John, and theymos has never once asked me for any personal details, and I've never offered them, and probably never will.

Moderators are given the option to either give sufficient personal details for theymos to complete a 1099 (a US tax doc) to report moderator earnings to the IRS, or to have 1/3 of their moderator fees be withheld and sent to the IRS. I would assume this is why OgNasty has given theymos his personal information/dox considering that he receives payment for holding the forum's money, and that other treasurers were given similar options.
I would however agree that the majority of escrows would not be willing to give up this information, and a good number of them probably do not even have any of the types of accounts listed in the OP. A major feature of Bitcoin is privacy and many people who use Bitcoin value their privacy. Plus even if an escrow's personal information is publicly known, money could still be stolen by such escrow if they were in need of money -- just look at MtGox, Mark's personal identity was public but that did not stop him from embezzling money from Gox customers.

Requirements are:

Billing address

What is this for? So I can send a bill when the escrow steals money from me.
These should be all authentic and not a fake or an alt.
How is someone suppose to verify this? All of the above are commonly traded on here and elsewhere. It is really not all that difficult to get a mailing (billing) address anon
