TCL, likelihood, I would say. I was literally just wondering that- and this would never happen, if the rules were actually thought about...
But I wonder what percentage of mods would delete a post, if "in doubt", and how many would leave it, if "in doubt". We would obviously all prefer it to be left- but with no actual guidelines or reasons required... it goes without saying- that all mods are likely to make different decisions- and that all posters are likely to wonder, ask and derail.
I personally have no issues with mods or moderation here- except that it is obviously so irrational, as there is it each to their own.
