What makes something spam and when should I flag it?
A post should be marked as spam ONLY when it contains an unsolicited advertisement.
It should NOT be marked as spam when:
The answer contains no useful information, such as an answer that says "I don't care about your problem". Flag an answer as 'not an answer' instead; **if you find a weird non-question, then flag it 'for moderator attention' with a custom explanation.**
