How do I delete someone else's gallery?

Base +7, darkkrisse +7, scribeman +7, archmancer8 +6, Fragmandk +8

First you'll need to check the wiki for expunge reasons and hope one fits.
Unfortunately, as terrible and low quality as this is I do not believe it fits any of the expunge reasons.

Though speaking of the wiki, the uploader should familiarize themselves with it and learn how to properly name their galleries instead of just throwing whatever random shit up as a name. (though that's not an issue limited to just this garbage and really needs to be cracked down more on. We've got a standardized naming convention for everything, takes all of a minute to learn and to many people STILL ignore it.

Base +8, scribeman +7

is...is this from some game?!
