I gather some statistics about OSM user activity at previous months and now I found the abnormally large number of new registered users without any changesets.
The names of such users seem be generated Jack838n0kt2 Michael393z5ah8 Owen1x37jar1
The current speed of registration is about 3 users per minute and more than half of it have a such names
Some users have only a spaming description

http://api.openstreetmap.org/api/0.6/user/4500001
http://api.openstreetmap.org/api/0.6/user/4500002
http://api.openstreetmap.org/api/0.6/user/4500005
but many of them have nothing.

Who are those people without changesets?
Spam bots or just forum or wiki users?
