For users disabled because of bounces, I think it would be a better way to not remove them from the list, but only set them as "disabled" optionally with a "disable reason", so you can check the problem and re-enable them.
Maybe also a "purge all disabled" action to clean up remianing disabled users when you want to get them removed for real.
