Blocks that resulted from a list subscription should be removed if a user removes that list subscription, or if a user is removed from that list subscription by the list owner. Currently, the blocks are converted into self-owned blocks.
Cleanup is difficult.
Subscriptions can currently add 250,000 blocks. Cleaning up these blocks manually requires a user to unblock 500 accounts at a time, repeated 500 times. It is also difficult to do this mass cleanup without inadvertently removing personal blocks that a user intended to keep.
