Short version: put a small flag based on the location a post originated from (not the user's account) in the header bar of a post. The idea is that shills/shitposters/etc slip up with VPNs from time to time, and it gives a way that someone can ruin an aged account by accidentally posting from e.g. Israel.

I looked into how 4chan did it to see if I could help it along over here; it seems they use one image with every country flag in it, and serve just a small portion of the image based on a country code. Here's their image: https://files.catbox.moe/mots3b.png

I mentioned this to Cynabuns who suggested posting it here: https://www.voat.xyz/viewpost.php?postid=609273351f6b7&commentid=6092d2da6189c
