Just another bit about what the site is confronted with.

The most popular username is: jamesfew (!)

(ok it isn't, it's a username that's used by automated scripts that keep trying to create accounts with that username )

First, during May and June there were about 600 "captcha" failures (the "I am not a robot" checkbox you have to click),
from all over the world.

Then, on June 16th an account with this username was successfully created (!)
Sadly, James hasn't solved any puzzles yet.
(why sign up then, I ask ).

And given the apparently insane popularity of this username, since that date there have been another 2000 attempts or so to use it for a new account.
