nicewash 

When someone/something demands that every interaction be positive. Negativity is not allowed under any context.

Don't go on Reddit to complain, that place is being nicewashed and you'll be banned for any opinion that isn't spun into happiness and rainbow sunshine.

nicewashing 

when someone deletes critical or bad comments below their posts on social media to create the impression of purely positive reactions...

Elhotzo nicewashed his comment section by deleting Don Elektro's critical responses and therefore proved himself to be a Nicewasher, who is nicewashing his comment section.
