I understand that many users of TeX.SE are scrimpy with their downvotes, but please don't upvote non-answers (e.g. comments erroneously posted as an answer) above a score of -1.
As you can (not) see in the picture below, a post with a score > -1 is missing the delete button. This makes voting to delete such posts unnecessarily complicate.
In particular, please don't upvote them above a score of 0, then even the unanimous delete votes of 6 users won't be able to delete such answers.
