Giving advice via social media (and other online means)

Considering new approaches to provide advice in the current situation.

I know this has been considered in the past, but as far as I know there aren’t any welfare advice organisations that give advice via social media - via Facebook messenger for instance. CAB went through all the trouble of designing their own chat service for help to claim…

Shuffling through the ICO guidance today, and especially given the current circumstances I can’t really see any significant issues, including against recording and processing special category data.
I can see issues, sure, but none that outweigh the accessibility of advice provision it could provide.

Are there any particular reasons why this isn’t done?
