Very simple, Jack's conduct.  First, a few years ago  caused massive disruption by posting  thousands of lines of mostly obscene juvenile, sexually orientated content.   (He signed these  using  other genuine posters signatures  and/or  his newly invented "friends".  
.
 All him, easily spotted due to his  limited vocabulary)
.

And now his unwanted cross posting of spam adverts for his Filedot Premium content.
.
He also gets paid by Filedot for the downloads of the 5th Rar

Jack is only here for the money, so please do not follow any of his links.
