I go to StackOverflow, click Users, and type "Jon Sk" in the box ...
There is only one, and he's the real deal.
I try "Jonsk"
There is only one, and no one would confuse "Jonskichov" for "Jon Skeet."
Where are these imitators of which you speak?
Per gnovice's advice, I have seen the one (still not a "surge") other user with the name, "Jon Skeet." His profile can be found here.
It's still not a surge of imitators, and whether or not the guy is imitating (the web site is google.cn, so who knows), does it matter? We'll all know the difference:
- Gravitar image
- The writing styles are nowhere near similar. (The real Jon Skeet writes professionally; this user ... doesn't.)
Bottom line: I'm not seeing this being an issue. Now if anyone starts using his head shot, or updating their profiles to mimic his, then there's a problem. If you really feel it's a problem even without that, then flag for mod attention.
I am now convinced that the user to which I linked above is definitely fishy. His name just changed to "Non Skeet" in the last minute or so (I refreshed his user page and it changed); his "standard" gravatar changed appearance sometime this afternoon (Central US time). Jonathan Sampson has called him out on impersonation, as well. Both questions I linked to in this post have been deleted, but based on them, I'm getting fairly convinced we have a prankster on our hands trying to disrupt the community.
