uuuuuUUUGGGGH at some point i should write an Actual Post about why social media discouraging cross-posting and automated cross-posters is bad but that sounds like WORK and i dont WANNA
the short version is that if you're someone who needs to Post to make money, crossposters are an easy way to make sure that even sites that are low-traffic for you get to have your work on them
i understand why devs and moderators might dislike them but each time someone has to figure out formatting for a different platform its like exponential more work. whereas something automated means that you can still build an audience somewhere, which eventually would allow you to potentially switch over to that platform, especially if, for instance, once platform was widely adopted but ethically vile or run in a short-sighted way, but another one is built more for long-term growth but has slower momentum
also, if you can't tell i formulated most of these arguments about mastodon which has/had the most asinine attitude about crossposting imaginable, if you have an official crossposter you the website owner get to decide what it can cross-post and how it looks which means you can take most of the stuff that annoys you out of it!!! people will cross post as much as they can anyway because see above about how much extra work it is to do that manually!!! that's human nature baby!!
