I always try out advice to see how it fits before passing judgement, even when it's a little snotty sounding. We all have our cranky moments. Anyway, I thought for a bit about talking about myself in an advice sub, and I will continue to reflect on this because I'm interested in the idea that the culture has shifted on this in the past few decades more than I've realized. I'll be paying attention just because. It used to be considered polite and reassuring to offer personal anecdotes when offering advice, but everything is subject to shifts over time. So far, here's the results of thinking it over just a bit:
It's human nature to be a little bit harsher when judging the faults of others, when we are sub-consciously recognizing elements of our own faults. I think you're overcompensating for something you're judging and controlling in yourself. I think it's still considered okay to include personal anecdotes as a way to provide context for the advice being given. That way, OP has the chance to compare and contrast my experience with hers, to help her determine how relevant my advice is. Like you said, only she has the details that will inform her. For all we know, they are both stars in the porn industry and she's wants her contractual percentage to be honored.
But I don't really to encompass all the random possibilities like I did when I was younger. I'm 56 now, and I'm utilizing a more honed awareness than I had when I was younger. I think OP is radiating signs of insidious, ongoing abuse. I think these signs would aren't so easy to spot without having significant personal experience. I want you to think about this for a little bit! I also want you to know, too, that the advice we give others is almost magically honed to our own needs. Go ahead, it's like magic. LPT. Give advice and then a moment later go .... hmmm. You will be startled at how ingeniously it can actually fit your own needs and seriously up your own game.
PS: I always do a little research into comment history before responding to posts like this, and I may have a bit more to go on than you realize.
