@Elenna searchtodon's (https://social.pixie.town/@f0x/109677935611759965) only option to not end up in the index is taking action to opt-out by adding something to your bio, or changing a (rather hidden) mastodon setting for your profile.

The correct approach would be opt-in, having people actively consent to indexing by putting a clear-purpose hashtag in their bio when they *do* want this
