I, personally, have been blocking the users submitting the spam. This isn't a good solution, but it does clear my feed out and make it so that I forget the spam is there until I see another user I need to block.
The other thing I have been doing is submitting content to my favorite magazines - if we actively engage the mags, we can force the spam down.
Did you read the article? "MCU" appears nowhere in it and Sony is mentioned 10+ times. This has nothing to do with the MCU whatsoever.
