So this website is apparently get ban from my country, and I dont know how I still get to use this website.
So the story is I forgot my phone password and I need to reset my phone, and when I reset my phone and all done now Im opening this website and it said something like this website have something illegal and not allowed in my country. I ask my sister whos using this website too and she said yeah this website get ban long times ago, so I use vpn and it work perfectly. And weirdly, when I log into this acc, I didn't need to use vpn anymore to open this website and work perfectly without the vpn but not for others people in my country. Im sorry if this sound so so confusing
Is this actually fine? Like Im just worried fbi are going to catch me or sum/hj
