According to the Hollywood Reporter, the feature “let users hide text or images that spoil a piece of entertainment (or anything that can be spoiled), simply by marking it as a spoiler.

Threads is testing a new feature that lets users blur parts of their posts containing spoilers. It's a good step towards making the platform a safer place for users wary of spoiling new shows or movies for themselves.
