I will never reject a previously accepted level unless it is requested by the designer or there is a very, very serious flaw that for some reason was missed. Of course this isn't a very good level by today's standards and would not have been accepted today, but I still won't reject it. However, I can understand your rating, though I personally find it a bit harsh.
It's a very old level, this is actually a pretty good level in five years ago, so voting it 1 isn't really fair Besides, most accepted levels won't get rejected, even though it's an old level.
The standards were not as high back then so the majority is now mediocre at best.
