Just noticed that if I delete a user from CB, none of the CBsubs integrations get run. For example, I have an SQL statement that subscribes a user to a forum when they register via CBsubs. I'd think that when you delete a user, that it would also expire them from CBsubs and fire off those integrations. it leaves a mess in all of the extensions that are integrated such as Acymailing, Kunena, etc.
CB 2.3, CBsubs 4.3, PHP 7.1, J! 3.9.X
