I seem to receive a lot of spam offering me helpful “advice” on how to make my site better. One was a particularly long and condescending message about how I was using SEO (Search Engine Optimization) incorrectly. I note that WordPress files these emails as spam. Rightly so. When I’m looking to improve this or that about my site, believe me, I’ll go seeking advice from people I know and trust.
In the meantime, a lot of those messages are going to stay in the spam folder, where they belong.
