DoNotLink if you want to link to anything on Polygon or Kotaku (or really, any gaming journalist site these days.)
If you want to let these terrible sites know how you feel about their shitty exploitative practices;
Polygon’s contact form is here
Kotaku is email@example.com
The writers of the polygon article are @Charlie_L_Hall and @danielleri
The writer of the kotaku article is @LukePlunkett.
If it really bothers you, let them know. Don’t threaten them or make personal insults though, it just gives them an excuse to ignore everything they get.
