Find rare pokemon, breed said pokemon, send out boxes and boxes of rare pokes out on wonder trade.
The idea that it might make some idiot kid's day, getting starters or pseudo legendaries, or save someone else from having to wait for weather SOS, makes me feel good about myself. Island scanning every day, breeding and sending out mons 90% of kids would otherwise never find makes it worth the deluge of first route shit mons the kiddos send back in return.
