Pool

Say you have a group of images that you want to represent as being "together" in some way. Either they're part of a set of variations, or they're pages in a comic. How do you keep them together? Many boorus resort to creating a "pool", a group of images that its users have decided should be grouped together.

Unfortunately for PTR, many of these boorus use arbitrary numbers for their pool ids, and such they can overlap with each other. Thus, they cannot be considered reliable unless disambiguated.

If you want to make your own pools, please do so locally. If you want to designate pools that found on boorus, the current suggested solution is to append the booru which issued the pool id after it, such as pool: 23685 (e621).
