The 9:1 self-promo rule is a myth

The 9:1 self-promo rule is a myth
This week on Reddit marketing, the most-quoted number gets corrected:

— [Rule-change] There is no global 9:1 ratio. The widely-cited reddiquette line about "10% of your posts" was retired from the official wiki years ago; mods now enforce per-subreddit caps, not a sitewide quota — sourced to the reddiquette page history on r/help.
— [Tactic] What actually matters is each subreddit's own self-promotion line in the sidebar wiki, which ranges from "zero links ever" to "flaired Promo days only" — credit to mod write-ups on r/modnews.
— [Case] A SaaS founder on r/Entrepreneur showed a clean 1:1 contribution-to-link account still got banned in a strict sub, because the rule there was "no self-links, period."

Editor's pick: read the sidebar wiki, not the folklore — the ratio that gets you banned is the local one.
