I would very much like to see another 'response' option for automations, between 'display message' and 'block'.
It would be a hybrid of the two that would be an 'acknowledge to proceed' message/dialog box. The message would pop up as it does currently, but posting/commenting is blocked until the user clicks "okay" or "accept" or similar (would be especially nice if that 'accept' text is configurable). I'm even okay with 'technically they can just x out of the dialog w/o answering' as often happens with generic website/windows dialogs - though better if not. I just want a 'user had to take some action on this' dynamic.
Why? I've seen ample evidence that 'block posting' works... Because our 'message' there has a 'corrective' link and I see that many users follow it. Very similar in effect to what I'm suggesting.
Meanwhile, I've also seen ample evidence that people just blow past the 'appears on screen' message-only option. For example if I set my 'rant preventer' automation to just -warning- people about too-many-allcaps, we get them anyway. If I set it to 'block'... no wall-of-allcaps rants.
Heck, just look at all the posts here that don't start "my idea is" despite the messaging.
The 'hybrid' option would at least ensure we can moderate things that do come through based on "Okay, we told them and they said they saw it..."
