I've proposed uninstalling the UploadBlacklist extension from Wikimedia
wikis. My reasoning:
* it's a very small extension whose configured blacklist, as far as I'm
aware, hasn't been updated in years;
* the AbuseFilter now supports blocking uploads based on SHA-1 hash;
* I don't consider the blacklist particularly effective as it's trivial to
bypass (intentionally or accidentally); and
* uninstalling the extension will help reduce, ever-so-slightly, some
On the relevant bug, Andre suggested that this needed further discussion.
Please comment on the bug or on this mailing list if you have any
objections or foresee any issues with uninstalling the UploadBlacklist
extension from Wikimedia wikis. Otherwise, it's a largely painless
procedure to uninstall the extension that I'm hoping we can move forward
with in the next few weeks.
