I wonder if Cryton4 has been blocked from editing the Wikipedia article?
Wikipedia shows that Cryton4 has not made any edits since 16:41 on 15 February 2010
A wikiadmin put some advice on Cryton4's talk page on 20 February suggesting that the user be more cautious over a possible conflict of interest but nothing else has been added to the user's talk page since then. Then again, this kind of step is usually one of the first things that a wikiadmin would do to nudge a new user unfamiliar in the ways of wikipedia in the right direction.
It would appear that no formal blocking action has been taken, and the person behind Cryton4 remains free like any other user to edit wikipedia articles as they see fit
