It doesn't read as emphasis to me. It reads like the person is trying hard not to curse, and they think "crap" is a curse word. It's a little bit adorable, like I'm reading a comment from an obedient child.
I grew up texting. But in the 90s any profanity filters could just be turned off in settings.
Youtube is a lot more guilty of it though, as well as demonetizing.
YouTube has its problems but I don't think it's had quite as strong of an effect on language.
I've never had texts censored by texting providers, they're not supposed to read texts in the first place (at least around here).
Even now I wonder if I am allowed to type bitch here...
I guess we will find out.
