Don’t put blinders on. The problem isn’t new accounts (who can’t even flag). This community has always been subtly in favor of exactly this kind of suppression. Consider the fact that posting anything even slightly critical of YC on the YC subreddit gets one instantly shadowbanned. Then consider that this very community is modded by the same ilk of people.
What would you expect? The same kind of censorship, right? This is by design. The design can obviously be changed (e.g. don’t let only echochambery high karma accounts vouch for stuff).
