So here's a question that's been bugging me for a while. I'm not entirely sure what to do about things like posts #190237-190246. It's a series of images, all pretty much the same with some editing done so that sometimes there's a ghostly dick, sometimes a ghostly finger, and sometimes jizm. True, they're (somewhat) different images, but the edits are similar to taking a picture of a dickgirl and removing the dick. And yes, they depict very different acts, but a dickgirl and a female are very different sexes. Part of me thinks they should be all linked as children to the first post, but then part of me thinks they should be put into a pool, since it's an obvious progression. But if we did that, we'd have a billion more pools, as there are a billion of these little 6 image series. However, then you could click on the first one and go through the rest with a single button.
WHAT DO?!
TL;DR When is it acceptable to leave nearly-identical-but-slightly-modified images out of parent/child relationships, and why?
