(TL;DR What kind of rules should we have for large wiki/image imports?)
While this isn't very frequent and not something I'd worry about yet, I think we should start considering a fair use policy.
This would mainly affect imports and, as an example would make it harder for a user that is the single user on a wiki be able to request a large amount of Wikipedia pages for import, or for example a single wiki to request say 30 GB worth of images. Currently we do tend to ask questions or refuse such requests but there's no clear guideline or policy. For example, right now I've started an import for 15GB worth of images for a wiki. I wouldn't say that's too much but we do want to think about these things in general.
Therefore, we should start thinking about what kind of policy we want. I'd not personally be in favour of any maximum limits for imports/images at this time, but I would be in favour of some sort of policy or constraints. For example maybe having a few questions that people need to answer when requesting an XML import or image import (i.e. How many active users are there on your wiki / Why do you need this import / do you expect many contributors, etc.). And maybe if we do want some sort of very minimal limit we could perhaps require (or in practice only accept) very large imports if a certain amount of active users exist.
Any other ideas/thoughts?
