The description of the "it is offensive, abusive, or hate speech" flag is this:
This answer contains content that a reasonable person would deem inappropriate for respectful discourse.
However, shog posted that said flag is correct for "someone [who] is abusing the site by posting gibberish." Therefore an answer such as
Me love lorem ipsum. lorem ipsum! lorem ipsum!
fits nicely into "abusive". However, the inline description of this flag remains unclear. I would still be flagging these as spam if it weren't for this answer.
I propose that the wording of this tag is changed:
This answer contains content that a reasonable person would deem inappropriate for respectful discourse, or is irrelevant gibberish.
Notice: irrelevant gibberish is still to be welcomed on meta... if you're a reasonable person.
