Question for Forum Admins (Membership numbers)

[fastboy21]

I was playing around today on the forums and I came across an interesting question:

On the homepage the "newest member" is listed as "nipslan" (welcome nipslan!). When I click on his name URL of his account page is:

https://www.project1999.com/forums/member.php?u=183803

The u=183803 denotes (afaik) the number of his account...meaning that he is the 183,803rd person to make a forum account on the p99 forums.

My number, for example, is 823. Nilbog is 3. Rogean is 1.

The total number of members is 111,405 (this is found on the homepage).

What is the gap between 183,803 (nipslan) and 111,405 (total members). Are the missing 72,398 accounts all banned?
