Why do I get emails from communities which I am no longer part of?

Hello BBS members!

Last week I received for the first time a reminder email from BBS, saying "they have missed me" in the Crypto Gaming community. This is a new feature of BBS to remind people about it and to bring them back to the communities they were active in before.

When I received that email last week I immediately left that community because at the moment it is no longer funded and I have no intentions posting there any time soon. I left by clicking the "Join" button and confirming I wanted to leave. The "Join" button is again blue which is a proof that I have no longer joined that community.

This week, more specifically today, I get again a reminder email from the same community:

This seems to me like a bug to fix... Why do I get an email from a community which I am no longer part of? When I leave a community, I do that for a good reason and then I don't need to get any emails about it anymore. 

Also why is Crypto Gaming the only community I get an email about? When are those emails sent? After how long period of inactivity? Anyone knows?

All answers welcome!
