This was true 10+ years ago on reddit. You look at modern reddit though, most of what is being posted is by straight up content farm accounts vs genuine user content. Not all of them are even laundered through shill accounts anymore. Somewhere in reddit history it became fine for users like /u/sfgate to emerge and have some sfgate intern post sfgate articles as sfgate directly. That is still against most subreddit guidelines but no one cares anymore. Reddiquette is dead, none of the admins or mods care, and the userbase has forgotten it too.
The failing is of course OP gets caught up in it, all for sharing something genuinely potentially interesting they made as a creator. Meanwhile, various mass market agitprop PR departments and media companies suffer no issues being able to post disingenuously on modern reddit.
