A couple weeks ago I blocked a reply guy who was persistently hounding me to edit a years-old blog post of mine to fix what he regarded as "grave errors".

It's like he never existed. I'm sure he's complaining about me, but it doesn't matter, because he no longer exists.

People try to tell you it's somehow "bad" to block, but you get to curate your own feed however you want. Don't be shy.
