From the bio I’m friendly. I don’t bite. Feel free to say hi.

That certainly doesn't match the Open Letter.

Recruiters are there doing a job, and it's not an easy one. I have a lot of sympathy for them. Treat them nice, because at some point in your future, you'll be looking for a job too. The ones that you treated well ("This job isn't for me, but try calling X who is looking") will remember it.
