Uhm apart from this wanted or unwanted highlighting of posts above 25 likes, that thread you initially mention also has half of the OPs text "highlighted" (compare MentaL's post with this one). That's usually not the case with that like highlighting.
Can a MOD please move this to feedback section instead of bugs? Since it isn't a bug, but a feature.
However, I still want feedback than that it looks pretty bad and it can be improved with like maybe glitters over the post instead of a really glitchy looking grey colour change, or change the grey to something more appealing that make it show much more its a "premium quality" post.
This are the places what I think look especially bad:
Also, I wasn't aware that a topic was already made regarding this. Sorry about that.
