I don't believe I had blocked anyone until I became an editor for You Know Where. Insufferable behavior there is not only tolerated, it's encouraged by allowing it to happen in the first place and then not correcting that behavior in the second.

That's when I started blocking. I'm not taking shite from anyone for any reason let alone for free by a non-writer who thinks they are indeed a writer.

Since I no longer edit for anyone other than myself I think I may have blocked a couple but not many. I'l allow a comment, my response, and then if there is an additional response from them and I can see it's escalating? c'ya. Life's too short.
