What private messages do you avoid answering?

Any that only say "hi" or "hey" or something equally dull and unimaginative.

Almost any from someone I've not interacted with on prior public posts.

Any with a photo attached from someone I don't know.

Any that are of a sexual nature without prior conversations.

Any that are asking for money, for me to breastfeed their husband (yes that happened), smell their diaper, or any other freaky shit.
