Almost literally every single social media site in the past ~15+ years has had those exact terms in it.
Everything you upload, almost everywhere, can be used by the site owners to do whatever they like for their own purposes (reselling is somewhat often excluded / non-transferrable). There are a handful of exceptions, but they're very much exceptions, not the normal rule.
HN maybe?
HN terms: "By uploading any User Content you hereby grant and will grant Y Combinator and its affiliated companies a nonexclusive, worldwide, royalty free, fully paid up, transferable, sublicensable, perpetual, irrevocable license to copy, display, upload, perform, distribute, store, modify and otherwise use your User Content for any Y Combinator-related purpose in any form, medium or technology now known or later developed."
Dude…just read them!
