i think in part it works like a lottery. simps pay, they post messages, maybe she notices it, maybe she replies, maybe she says their name. it makes them feel like they have a shot. rationally they may or may not be aware that they don't actually have a shot. the odds are so small it's not worth considering. they don't even really interact with them. the random simp just has a tiny tiny tiny bit of influence on like a few seconds of her day. but it doesn't matter. lotteries are still popular. when they buy a lottery ticket they like to imagine themselves getting rich. same thing with simps and e-thots i think.
