I have created a post on the disposable email blocklist's Github requesting he remove Spamgourmet domains from the list. If any other members could go there and comment with your own personal experiences and reasons for using SG we might be able to get their intention. Be sure thumbs up the post as well.
PLEASE TAKE THE TIME TO REPLY TO THIS POST ON GITHUB!! (Speaking of which, Github allows SG domains)

Thanks all, this is obviously a long shot, but it's kind one of the last things we can do on our end with Josiah MIA.
Thanks,
