IMPORTANT. Threads stated policy is to collect and exploit Fediverse user personal data without explicit consent.
Now is a very good time to review Threads Terms of Use (https://terms.threads.com/terms-of-use) and Supplemental Privacy Policy (https://help.instagram.com/515230437301944).
Note just by following a Threads user or replying to a post, Meta claims they are entitled to your personal data.
And what do they say they will do with your data? Provide you with "business services (including ads)."
