Purge community membership lists when community is deleted
Short, concise description of the idea
When a community is deleted, first purge community membership lists, so that situations such as this (it's happened before and I just spent 20 minutes looking for the other support requests, which of course now I can't find).

i thought if the community was deleted it just doesn't show
but it might be broken if the community is purged

Nope, if the community is deleted, it still shows in the "Shared Journal Access" list for users. I'm still trying to find the support request that was open for ages about this problem, as it had a lot of good info, but wading through the ten thousand closed support requests takes a long time.

I do know that the last time I saw a request about this issue, the community in question had been deleted only about a week prior to the request, so it wasn't a problem with being deleted & purged.

Another solution: simply change the user profile page to not display deleted communities in the shared journal access list.

That works too, but if username recycle ever gets turned on, people might be able to create new journals/communities with people already subscribed because of legacy membership. I think it's better that if the journal is deleted/purged, the membership lists should be deleted/purged too, for internal consistency.

usernames may be used over again, but userids would not be
people belong to a userid, the username belongs to the userid... so when a username is reused, it would change to the new userid, but the memberlist would belong to the old userid (confusing way of saying that wouldn't be a problem)

the userid for communities can be found using the finduser command in the console. leora mentioned this the other day, and it suddenly became incredibly obvious :p but it's not a good solution for the problem, because not everyone is going to contact someone with finduser to be removed from a community. but, it is possible.

what about suspended communities? same problem. 43998
