I lurked on their chat three times, and noticed that the same users said the same things, with different timestamps.
Looking closer, exactly the same messages were "exchanged" between other "users", and in the same order.
I'd say they were playing back recorded chat, or some kinda bot was at play, teasing so it looked like there were dozens of users online.
BTW a recurring message from a bogus female invited others to visit "her" website, where it turns out to be a porn-for-dollars rip. This invitation appears every few minutes in every chat "room". Attempts to block this user were ignored. Interestingly, the porn site is listed as one of their sponsors.
