Users sometimes stay conversation participants after leaving group

[tiltec]

Just opening this issue to remember in future. I used this query to find affected conversation participants:

ConversationParticipant.objects.filter(conversation__group__isnull=False).exclude(conversation__group__members=F('user'))

Currently there are over 30k results on karrot.world, most of them activities, but also applications, places and offers.

Need to figure out if they are actually wrong, how this happens and how to clean up.

Now I noticed an old issue I posted about this was closed by the bot. I can confirm this problem:
#2411

This issue is marked as stale because it has not had any activity for 180 days.

If it's still important for you add a comment saying what it means to you, remove the stale label, and/or add the "important" label :)

However, if you just leave it like this, I'll close it in 30 days to help keep your issues relevant!

Thanks!

Got this issue confirmed in practice yesterday... I wrote at a place wall and a person who's been previously voted out of the group got the e-mail notification about my message and was able to reply it by e-mail, so their answer ended up on the thread.

I think it's a very important bug to work on and should be prioritized
