When we had clockspace on our clock crew website, you needed to link your Newgrounds account to your clockspace account for it to work.
We had a simple method of ensuring that nothing gets screwed up like non-existent accounts getting tracked, basically, you had to change the website link on your newgrounds profile to a uniquely generated clockspace link, and clockspace would check the account for the link.
If the criteria was successfully filled, you got an active clockspace account.
That would certainly prevent account name guesses.
But yeah, it's very much difficult to track files to see if they're malicious or not, which is hard since some horrible people exist on the internet, even on Newgrounds.
As for the genuine FLA/SWF checks, I think something called MIME types makes sure what file is what regardless of file extensions, I'm not sure.

An animated gif will always do. :3
Also, I saw about your uploader on your site.
Why don't you just implement an account system similar to that of Newgrounds Log? That way it restricts the flash project uploading to just Newgrounds users like you wanted.

I don't think there's any way to check whether a user is genuinely a NG user or whether they're just faking the username. Casualty has no way of checking for genuine passwords for the NG Log, and neither do I. It WOULD cut down on the other-site users (although they could guess 'John' or 'Tim' if they have half a brain-cell), but even if it was just limited to NG users I'd still have the T&C-breaching file issue. I can't moderate the uploaded files. I'm thinking if it ever does get back up, to allow ONLY flas and swfs, and find some php or asp way to check whether a file is genuinely a swf or fla, and not a renamed exe (I assume there IS a way, since NG has checks for a real swf on the portal... but I don't know how, and I'd imagine James is snowed under with redesign bugs, so I'm not going to hassle him).
It's all a bit blah, I really didn't want to have to close it down
