@Ernest has pushed an update which allows users to request ownership/moderation of abandoned magazines. Ghost/abandoned magazines were fairly prevalent after the initial wave of hype due to users either squatting magazine names or becoming inactive for other reasons. Now is your chance to get involved, if you were waiting to do so.
To request ownership/moderator privileges, scroll down to where it says “MODERATORS” in the sidebar. There will be an icon of a hand pointing upwards that you can click on, then make the request. Cheers, and thank you for your hard work Ernest, as well as future mods.
If you didn’t get an answer elsewhere yet: You click the button and it sits pending until approved (whether its Ernest approving manually or an automated batchjob I don’t know). Seems to be once a day or so, so could be either but that’s just anecdotal. That’s it tho. Click the button and wait, no other steps lol.
Either way, once approved the magazine will just appear in your moderated list on your profile (no notification or anything from what I’ve seen) and from there it’s yours to do with as you want. I’ve claimed a dozen or so over the last day or so to delete (unused ones people sat on).
