I can't unfollow multiple projects I don't have admin access to

I keep getting emails on build failures on those projects.
Klicking the unfollow link in the email takes me to an error page on circleci.
There is no option for me to unfollow these projects anywhere in my account settings.

Also, I still see a github organisation listed in my circleci account, which I am no longer member of on github itself.

@zzak I see that you offered help on a similar issue.
Could you be so kind and have a look?
Thank you!
