Players taking IC as OOC is just something that happens in RP scenes. You'll even see it manifest on these very forums in the way people talk about their characters as if they are those characters. For example using personal pronouns when talking in OOC forums about their character (I, my, me) instead of "my character" or [character name].
One aspect you didn't touch on is something that the vast majority of roleplayers mix IC and OOC with all the time; not creating a separate mindset for your character that doesn't look at the world they live in through the player's very modern view
For example, most players in this scene takes being able to read for granted. All of us players were raised in a culture where literacy is extremely prevalent and the vast majority of roleplayers port this mindset straight into their character. In Eorzea being able to read and write is a big deal, but despite that most roleplayer's characters have little or no reaction when it comes to light that others are literate, in fact it's more noted in roleplay when someone CAN'T read or write.
Why? Because being able to read is just something everyone they know can do in real life, and because many players don't create a separate worldview for their character there is an entire cultural aspect of the lore that is largely left untouched and in fact the reactions to illiterate characters are often completely backward from what they should be; "What, you can't read!?"
Another great example of this mixing IC and OOC is traditional Seeker tribe lore. That is so contrary to a modern mindset that many players cannot discuss it without dissolving into a frothing rage.
OP seems to have a good handle on identifying the worst offenders when it comes to players who mix IC and OOC, but the truth is the vast majority do it in more subtle ways without even realizing it. It's just something you have to accept is going to happen in the scene while doing your best to navigate it.
Though I'm dubious about a raider being a red flag for you thing. I have a pretty solid coil static that clears everything and I am very, very good at separating IC and OOC so either it's just been your bad experience or I'm the exception, either way.
