If people ask you to use custom emotes to prove yourself and it doesn't fall under OGI, then using a browser console or userscript to figure out other player's emotes shouldn't either. Either make both OGI or neither.
i think the point is that that someone shouldn't have to use a userscript or the browser console in a normal game to guise as someone. i'd argue that using emotes to prove innocence falls under outside of game influence.
