This will only get worse as the incentives shift from purely "propaganda" to actual financial incentives. The SEO spammers are coming for Reddit. You'll start noticing comments that have been edited months or years after the original, that insert links for a particular product/service. I've already seen this for a variety of IPTV comments I was searching. I'd imagine this is mostly done via mass outreach. On a different note, I'd imagine the pushback had this been "right wing" propaganda being caught to be 100x with mentions of criminal activity, even more censorship, etc.
