Constituents can be removed and re-added by Support. To do so, please:
  1. Add the desired constituents to a group. You can do this either manually or create a query to identify the constituents and add the query results to a group. Note that if you want to reuse these groups for future requests, you'll want one group for constituents to reinstate/reactivate and one for constituents you wish to remove.
  2. Contact Support referencing this article and providing:
    • The group name (and group ID if possible)
    • The request (either to remove or reinstate/reactivate) for the constituents in the group
