BMF.io keeps things real by not letting publishers spam the feed with self-promo stuff. They've got rules that say "nope" to posts that are just ads in disguise. If someone tries to hype up their own product too much, users or mods can flag it. There's probably some tech that catches spammy words or links too. Basically, they want the content to be helpful and interesting. If someone keeps breaking the rules, they might get a warning or even kicked off.
