Just to clarify what i ment, the file has only been "encrypted" to the level of you cant read it in notepad, mirc just decyptes it, then treats it like any other script file, no one can hide bad things in it, as the mirc editor would show the text, just not let you copy and paste it from the editor window.
I can see someone who has spent a good amount of time writing say a trivia bot or something, not being particually happy with someone changing the name and saying theres is a new version, with 99% of the same code
