like shaming
As the title implies, shaming those for liking something, it doesn't even have to be a fetish at all, that's how fucked up our world is today.
People on chanboards will often do like shaming for even things that aren't cringeworthy at all, baseball cards, old technology, even alternate history will be like-shamed for some reason.
Shame-liking
The act of going on to LinkedIn to debase yourself by “liking” posts from your superiors solely for purposes of professional advancement.
The CEO just posted a thought piece on LinkedIn and it already has likes or comments from nearly every company VP. Forget customer service or innovation, our real corporate culture is shame-liking.
