Such user account: http://www.openstreetmap.org/user/2%20man%20tents
is created for google ranking. I've seen similars in the wiki and forum. What is the part of real user accounts in OSM. How can we believe the OSM stats about registered users ?
To avoid such things, one idea could be to disallow user's profile description until a first edit is done in OSM db (or, at least, forbid external URL's)
My 2 cents
