GPT-3/Open AI concerns

It’s been a bit (im very bad at keeping up with blogs) and i had a question about privacy and bot concerns.

With news that several comapnies are using bots to try and crawl the web and use peopes writing to train AI (see and i'm glad to have shared in your perils : r/AO3 - Sudowrites scraping and mining AO3 for...) are blogs and posts indexed? Are there ways to keep a bot from trawling our content?

I’d assume this woild concern p much all users considering theres a posisbility they could use user generated content on the site and profit off it.
