I think the motivating instances are largely:
Online debates are bad
Freedom Of Information requests suck
I think I probably backfilled from there.
I do sometimes get persistant questions on twitter, but I don’t think there is a single strong example.
Though sometimes the obligation to answer is right, right? I guess maybe it’s that obligation works well at some scale, but then becomes bad at some larger scale. In a coversation, it’s fine, in a public debate, sometimes it seems to me that it doesn’t work.
