Purging

[Durandal]

Get the snapshot DB of the forum that is 1 week old. Start exporting only posts made by Shiki then import those DB entries into the current DB of the running forum. Of course that would probably only be possible if IDs in the database tables didn't get overwritten or something after the purge. I'm not an expert here though, never did any MyBB administrating.

I don't do DB snapshots anymore as I now do the backups at instance level.
Basically I'd have to set up a whole new instance with duplicated volumes just to retrieve a few posts.

Alley, Shiki has been a member - or at least their forum account has existed - since May 19th, 2015. That's one year, eight months, and twelve days of time they have spent making roleplay, participating discussions, and having leaving their mark - for better or worse - on the community.

Yes, it's annoying. Yes, it's one person. Yes, I would be absolutely livid if I had to do it too. But a day of your time cannot possibly be more valuable than over a year and a half of somebody's personal history.

Set up the instance, retrieve the posts, and give Spazzy whatever punishment the admin team deems reasonable for this colossal SNAFU. There isn't any other responsible option you can take.
