They remove these ripoff threads because if they didn't, all their forum will be filled with  people ridiculizing ripoff posts, it's written in their posting guidelines to not post ripoff related things.

They only wanted to keep the forum focused on Kancolle, not ripoffs, since there are so many.

Either way, that might passively keep these bootlegs unknown to people.
