Are you looking for my AWB Bot; MifterBot I?
MifterBot is a bot operated by Mifter. It is written in Python. MifterBot's purpose is to check recently uploaded files. This Bot checks if a file
description is present and if there is only a {{PD}} tag in the description.
It will tag a file "no source" in the former case, and request the uploader
to choose a more specific license in the latter case.
