I just reviewed this low-quality answer and agreed it should be deleted.
I'm kinda new to this whole "reviewing" thing but I understand the basics of what to do and what not to do, so I clicked "Recommend Deletion."
Sweet! More fancy buttons for clicking:
I'm aware PPCG isn't a "typical" SE in its Q&A format, and so sometimes things are a little weird, but... which do I choose? It's really, none of the above. (I'm surprised there's no option for "This answer attempts to answer the question but is unrecoverably bad".)
I left the option as "no comment needed", but in edits and the comment section and other places SE make it abundantly clear that comments are encouranged and looked for when trying to quantify the validity of something, which makes me feel obliged to leave a comment.
It would be good if there were a little free-response box for me to type a valid reason, but there isn't.
What should I do next time?
Note that my question of "which option?" is not specific to the review in question: for almost no answer on PPCG would the given options be satisfactory.
