Onlyfans and GST?

i understand that i’ll have to charge GST tax on my content after making 30k

however, one of the main things of OF is that it’s anonymous. i have no idea where my clients are from, let alone if they’re even in the same country as me!

i’ve also been told that my content is already taxed by OF themselves when they go to make a purchase. OF doesn’t let me see any of that. if i end up adding tax to my prices, the client would technically be double taxed.

i’m curious if anyone has some insight? i’ve asked an accountant, and a liaison officer from the CRA that works with small businesses but they both seemed confused by the situation

i’m doing more research but any help would be appreciated 🙏
