For a long time we have endured spam from SomeProduct's company/owner/employees who post a lot of answers about SomeProduct in barely relevant questions.
Today they posted again about SomeProduct and guess what? Their answer is perfectly on-topic at that question, SomeProduct actually does exactly what the asker requires.
Being known spammers, they are not liked very much, the answer is now at -4 and has been flagged as spam. I declined the flag, because the post at its face value is on-topic and the tone is not spammy either. But someone else tagged as spam again, so I decided to ask here before declining again.
What should be our stance on this?
