"Check users for spam" button work differently

[Alexufo]

This button work very strange.
All users in result are real users.

In main_listener.php
if(sizeof($users[$cnt])>450) - this change array shift depends on user counts?
change 450 to 800 and result of "spam" will be less. Change to 300 - and "spam" accounts will be more.
