Indeed if it's the front end we can't do much, I'll share ecency only and see if that happens on it too... I'm pretty sure it's not reddit api issue because I delete the history post and remade it some time later and still didn't get caught
I'll keep testing and trying to catch what have in common shares not caught, for now the front end is a link
edit: i just shared this now from ecency and didn't get caught too
