In the past two days I have run across two one-line answers that were not in English. One appeared to be in Spanish, the other in Hindi (to the best of my ability to tell; I don't speak either language). I used a custom flag for the first, and "not an answer" for the second to avoid bugging the mods, but I'm wondering if there is a better choice.
Specifically, my guess is that both are actually spam (I can't imagine another reason for such answers), but I can't tell for sure. I know that the consequences for spam flags are higher than for some of the other flags, so I'm reluctant to use it in an unclear situation—but on the other hand, perhaps we want stronger consequences for such posts (assuming they really are spam).
I used the custom flag the first time around so a mod could make the decision, but if this isn't going to be a once-in-a-blue moon situation, I'd rather just know what auto-flag to use (or know that the mods think it's appropriate to use the custom flag).
