Log user out of Discourse when user removed in Memberpress

When a user is removed from Memberpress, I want to log them out of Discourse so they no longer get access there.
How do I do this?

Many thanks!

I have been anonymizing the user. So far, nobody has returned as a member, so this hasn’t been a problem.

I think that suspending the user better fits what I want to do, but I don’t want to email a suspension notice to a customer, because they might interpret it as somehow blaming them for canceling their membership.

I’m open to suggestions on how to handle this better.
