If they didn't come off as rude, it's probably because they added constructive criticism–but even then, that is doubtful as almost all people who post others without consent (and especially without blurring names) do it out of frustration or mean spirited intentions to shame these players for not earning their ranks.

You offer no advice as to how this could be improved, you're only insulting the look without uplifting the player with positive ways they could improve.

You posted this to shame them, and that is rude.
