Does upvotes prevent flagging as very low quality? In the first post review queue I see an answer, which I want to flag as very low quality. But when I click on flag, the very low quality option is missing from the list of options. The answer currently has a positive score of 1. Would that cause the very low quality flag to be made inaccessible?

Yes, the very low quality flag is available only for posts scored 0 or below.

In any case, you can't flag that answer because I already deleted it.
