I have yet to read a good argument of why we don't have a Delete Submission button. Yes, you can email Wade, wait 5 years, and maybe have you submission deleted. This makes more work for Wade, and it isn't guaranteed that your submission will be deleted. Over the last few months, I've emailed Wade like 12 times to delete my submission... and it is still there. Another argument was that people would delete good movies they made. I don't see that happening. The reason many want to their delete movies is for the simple fact that they suck. It might have been one of their first submissions, and maybe it reflects poorly on their actual skills. If it brings their batting average up, so be it. That doesn't really mean shit. Now, addressing the hacking accounts argument, there is one simple solution; MAKE A REDICULOUS PASSWORD! NG has almost no loop holes or php flaws, which makes fucking shit up very hard. One of the only ways to gain access to an account is to know a persons password. Even if someone did manage to get into an account and delete the movies, I'm sure they still have the origin .swf and can re-submit it. In conclusion, I think a delete submissions button would be great.
