Today, on the forum summary at the bottom, I saw this:

Most users ever online was 680, 30-06-2010 at 02:35 PM.
UncleZen, 1Barret1Lok, MduUyyqBug, MduUyyqdelo, MduUyyqHerb, MduUyyqKat, MikeW001, NicoT, Sticky, Umachan, WilliamZet

4 of those look like auto-generated usernames, used for spamming the site.
