My personal views:
The rise in popularity of Dnforum.com and new memberships being formed every day, I think the verification seal is a good idea. It would not have any affect over me doing business with a long standing friend/member here who I know to be legit ... however, I would feel a little better about doing business with a member I do not know or have never seen if they had been verified and that I know DNF might have a little piece of information on file that they otherwise would not.
I know it is impossible to apply complete trust in this, but I think for adding a little extra step of security, the purpose is well served.
Therefore my answer would be Yes and No as well.
My 2 cents.
