Yes, it sends us notifications. No, we don't view it as spam. I/we all greatly appreciate those who report it. We don't see everything, so it helps when members report things to us.
When you report a spam post, not only do we delete that post, but we ban and suppress all the posts from that user. So you may report 1 spam post, but it may end up deleting 10, 20, 30+ posts. You do make a big difference.
