Really, it comes from a bad experience. On a separate site, I have stuff on a similar voting scale and that stuff is at such a range even a single most random fly by votes of any kind just ruin my credibility entirely.
It not like the stuff is really good or very bad, but too many times has a rando past by and hit my stuff something to the point of me wasting time trying to keep said stuff alive. Random posts seem to always attack me, so when this site was getting on the idea of hating upvote beggars, I was firmly on the side against such random posting.
