Why Can Nobody Trade Honestly Anymore (rant)

I'm sure this has probably been pointed out before, but what is wrong with people? I'm trying to do some honest legendary-for-legendary trades so I can complete my collection in Violet, but the only trades in the GTS are either people offering baby mons or really cruddy ones asking for legendaries, or people offering legendaries in exchange for impssible pokemon. Why? Like, what is the point in posting a trade you know is never going to be accepted? Nobody is going to give you a Groudon or a Necrozma in exchange for your Pikachu.
