I help moderate a facebook group which gets a lot of attention from spammers - at least 90% of the accounts trying to join are bots. We filter them out by asking a few simple questions, which the bots cannot answer coherently. Someday soon, a spammer will get GPT-3 or something like it into the process, and then... whoo boy, that'll be the end of the group.
