OR, and this might be a stretch, we can expect people to understand the gist of the fucking meaning of the message when it is clear. English is second, third or even fourth language for many of the posters. NTR is widely used for cheating/sharing too and it's not just posters.
Game devs, modders, mods, posters, translators are all using ntr in different ways with the example below by
