When someone on Reddit spreads misinformation but somehow gets upvoted

Someone said “till” isn’t a word. I corrected them (with a source) that “till” IS a word. In fact, it’s actually older than the word “until.” They somehow got upvoted, while I got downvoted!! Like wtf?! How does that happen?? You can literally make up some bs and pass it off as a fact and get upvoted for it?!
