Many people use VPN and still use western models. Ditto for those looking to study abroad, the key point the audience we're dealing with, i.e. those who want to go abroad for school overlap with cohorts who will invariably have VPNs, so if a site doesn't work due to GFW, one falls back to using VPN anyway. Hence embedding senstive terms trying to get rid of PRC users who are used to leaping the wall (in this case literally) is stupid, like commenter posting copypastas in reddit or youtuber thinking it would kick PRC users when they were on VPN to skirt GFW filtering in first place.
