or are you judging him based on the 20% of his posts that you can read?
Try not to look at it that way. Look at it like "This is a red flag, you guys should check it out". If I saw that post I wouldn't ban him immediately, but I certainly would take a closer look. That's what reports are for.

One had 5 accounts, the other 19, all with similar posting styles. Spammers indeed.
