Just a heads up, there is a difference between an imageset and a compilation. This is the former but, well, how are people going to get their toplist from that?
Compilation expunges also require listing the sources for all compiled content instead of just a single gallery, you can easily recognize BS compilation expunges because they never follow this rule.
To elaborate on the difference between an imageset and compilation:
A compilation stitches together a bunch of sets/stories, insisting that its way more convenient to have everything in the same gallery (which isn't wrong......but its also a nightmare to tag and just flat-out not allowed as long as you can prove all of the content already exists in superior galleries.)
An imageset compiles random/loose images within a specific theme, like everything from a specific artist, cosplayer, circle, parody or character; or a curated collection of images for a specific fetish (or in cases like this, both) these images can potentially exist in other galleries, other imagesets in particular, but this should still be fine as long as it's bits and pieces instead of significant chunks of galleries.
