I'd turn it around. Has there ever been an instance of a CoC being used in an unreasonable way against an actually reasonable person? There's been a few cases that blew up because the behavior fell into an arguably ambiguous zone, but I can't think of anyone who suffered real consequences and didn't have it coming. Just a little more tact and thoughtfulness on the offender's part would have saved a world of trouble.

Now I'm of two minds on this. I do sometimes miss the more freewheeling culture of the '00s, and feel like the need for constant compliance has drained the tech scene of some life... but honestly it's a small price to pay if the only alternative is tolerating fascists in your midst.
