Have you ever had this happen?

1. You like/comment/RT a post on Mastodon from someone.
2. They like/comment/RT, have a conversation, and follow you.
3. You follow them back.
4. Their next post is something you don't feel comfortable with, not because it's factually wrong or bad taste or whatever, but because it seems...wrong. (This person as it turns out, hates old people.).
5. You click on their profile. You immediately wonder: who the fuck are you following?
