2: Your post was not locked for "spam" it was locked because you cannot post inactivity threads.
3: I am not sure what you mean but I can explain what happens with applications. Applications are looked through at the Saturday admin meeting usually around 7-8pm GMT -0. As long as your application is in before that date and time then it will be seen to and added to a powerpoint for us to view. I presume that was what you wanted to know.
I am uncertain about the sourceban question but I am atleast 70% sure that SourceBan is not used on ZARP.
Hope this helped
