Now here's explanation of his SEO spam action. ~ he edit his post some time after it's posted. Here's an example,
Good find (but wrong topic). This is just plan old spam. I've reported 9 of his posts:
Spambot, please Nuke. This user edits his posts after a few days to add a spam link.
Update: he's Nuked.
I don't know why you say wrong topic. But i consider it as SEO spam since the link have little correlation with thread topic or what that user said. Anyway, it's good to see this user nuked quickly.
