The great thing about being in the media be it print, tv, radio, or social is that you can be wrong over and over and over and over again as long as people are watching, talking, replying and following.

KD is the perfect person for Acho to throw shit at because he knows KD will respond, KD has a ton of followers who will gladly pile on to defend KD, and will be happy to link what he said all to prove just how stupid Acho is when in fact they are just widening the exposure a bit more at a time.
The world of media isn't designed to periodically purge itself of those who only stir shit up and don't really contribute, heck, the only difference between Acho and a good number of posters on the internet is he is getting paid for saying and posting such things and the rest are helping him getting paid.
