I am the person who downvoted. I am not afraid "to come forward", as many have speculated. I don't believe that I have done anything wrong, and I am rather certain I have not broken any rules. So why? The short is that I think that all those answers are bad. I'm not interested in hurting any persons rep or feelings. My reasoning for thinking these ...

Enforce standards for these questions I think a lot of the problem is that golf-this-for-me tips questions aren't held to the site's usual standards of clarity, completeness, and objectiveness. I know these can be hard for new askers to get a handle on, but we already require the same for challenges they'd post. Sandboxing should be strongly encouraged here ...

Best mathematical insight On this site we often see answers in languages specifically designed for short code, or designed to be fast. Sometimes, a nice golfing trick or speed-up technique surprises us with its ingenuity, beyond the standard use of that language. And occasionally an answer shows up that uses an unexpected approach to greatly simplify the ...

Wild card For a deserving challenge, answer or user that isn't a good fit for any of the other categories. I (@KevinCruijssen) nominate all @stasoid's answers for the Add a language to a polyglot challenge. This challenge was created in 2016, but @stasoid has been adding new languages every few weeks for the past 2+ years. It's insane to think that this ...

You shouldn't use moderator flags for this purpose -- I don't know what you expect me to do. Information about individual votes is private, even for moderators. Presumably whoever cast these votes is unlikely to look for a meta post asking them to explain their reasoning. Since there's no way to tell what motivated this, my suggestion is to shrug and move ...

It Depends In general, we handle reposting of challenges on a case by case basis. For this particular instance, I would argue that this KOTH challenge is OK to re-run, provided that someone can't just take the existing winner and re-submit it as a serious contender. In other words, there needs to be enough tweaking to the ruleset to make it a "new-enough" ...

Sorry, it was an accident. I had a little fiasco with my computer this morning and I must've pressed the down arrow inadvertently. Stupid touchscreen... If you make an edit I'll give you an upvote.

Exploiting the controller in a King-of-the-Hill challenge I'm surprised that this wasn't here before, but this answer found a loophole to exploit in the KotH problem that should really be sealed off. (The rules of the challenge at time of writing only forbade using code that modifies the controller or the other bots, so the bot in question returned NaN ...
