follow up question about tumblr hyperbole

Is it ok to use tumblr fake upset hyperbole in asks, or is that only for posts and reblogs?

I’ve only ever seen it used as a third-person kind of thing.

Like where SCREW YOU I DIDN’T NEED MY HEART ANYWAY is something you say about something to another fan of the thing, not to the creator of the thing.

Is that something people also say to creators directly?
