The Twitter UI/UX for accepting follow requests is a fractal of bad design.
For private Twitter accounts, follow requests must be approved manually by the private account.
The UX turns out to be so ill-designed, so slow and unusable, so error-prone, so counterintuitively frustrating, that I finally wrote up a list of all the problems I encountered while using it for my account.
The only way to ‘bump’ a follow request, to make it findable by being the most recent request, turns out to involve the requester blocking me for up to a week before unblocking & re-requesting.
