You should exclude the brand new users from your stats. They are likely to be spam bots that are banned.
That is quite some stat in itself, 73.35% of new accounts got nuked.
I agree that the other percentages would give a better representation with those having been removed from the figures first.
Ah dishonest Quicksy...

Speaking as someone who actually knows what they are talking about, most of the new users have not made any posts at all, and have not been banned or nuked.
I could pull up exact figures as needed, since I maintain a full list of the modlog.
