Doesn’t matter to me. I’m not wishing harm on anyone, whatever our problems are, assuming they leave me alone. Some people might be disgruntled if they were left in a bad position and then their ex does great. Others might think “hmm, we’d stayed together I could have benefited from a wealthy porn influencer lifestyle”. Personally I think if they can move on and be prosperous, great.

Assuming I really hated them and wanted them to suffer, I'd rather that they be super successful.

I'd want them to be successful enough that people not only have sexual fantasies on them, but also, deranged fans that stalk and harass them. The harassment, stalking, and the "pressures of celebrity" would also likely lead them into a downward spiral. Perhaps the only downside to this is that a crazy enough fan would abduct them, and kill them. If I really hated that ex's guts, I'd rather them suffer until they either spectacularly implode in public, or fade into obscurity only to resurface in the news as one of those "Where they are now?" articles showing their extremely sorry state.

Otherwise, I don't really care. They're not my problem anymore. They'd have far better chances of living a normal life if they were super unsuccessful, though, so there's that.

If y'all had a kid, successful. If she a hoe, unsuccessful.
