@Corsaka It's worth noting that this post is two years old, so there may be a newer version

@A__ Damn, it's been four years. Time flies, huh

@RedwoldPrograms This post is over a year old and I have not been active on this site for a long time. For all I know the may have been new issues that have arisen with the sandbox. All I know is that back in 2017 there wasn't a problem in my eyes.

It may be worth taking this issue to meta.stackexchange.com. The point you make in your edit is very interesting

What about cases such as “Where’s Blackhat?” where there are a limited number of test cases (never mind the work that one would have to do to compile many many test cases)? What would be the appropriate tiebreaker then? Code golf as a tiebreak seems like a cop-out to me

Do we need a meta consensus? We're just going to drive people away from this site if we keeping adding more and more obscure rules

We've been through this on chat: it's fine as long as I reveal the test cases at a later date. I don't get what your problem is
