Many people know it now but there is a well known Swat Equipment .ini hack (in 1.0) which gives the Pepperball the ability to have different firing modes - burst, semi and auto. Cheaters with this hack can switch the pepperball to auto mode, fire at any object in any map and crash the server effortlessly. By disabling this weapon altogether, you can reduce the risk of your server crashing massively.
