Are there any book bannings which you completely agree with?

I used to believe I fell into the category of free speech absolutism however recently I’ve started to come to a conclusion that some books have little to no redeeming value and can only cause damage to the reader and their community. Two that come to mind for me are Mein Kampf and The Turner Dairies.

Are there any books which have been banned which made you think “Good. That’s good actually”
