Collections was a thing long before H sites did them since some individual works are logically part of collections. Even if the layout looks similar it doesn't really matter, I've seen a few other H sites have a similar layout to this so the whole who copied who is pointless.
Fair enough, doesn't quite work with the current layout and the available features of this site. If you think it does, we'll agree to disagree.
There was a lot more behind the fall of Purpurin, it wasn't just the whole keeping up with the site. I remember lurking on there forums and reading about some of it, though I never kept up with it that much to really know the deal. Someone is attempting to clone that site to keep it running in essence and wish the best for them. I like purpurin as well, but shit happens. Most H sites take ideas from one another to make there site better, I've seen a lot of dummy sites that try to copy exhentai and fakku, but you just go with what you like really no sense in calling copy-cat lol.
I can't think of one feature I'd copy from Fakku, I'd love to hear what they plagiarized.

Or create a politically correct tag like "petite", vaguely hinting it's loli. Then again, it wouldn't change much given the next quote.
The blacklist tagging probably be a premium feature of the site.[/b] Fakku is working on a monthly membership called Fakku Gold which will have such a feature along with other perks, though it is still in the works.
I don't know where to begin about the ramifications of such a move. I honestly got a headache from reading it.
