I was trying to move to commons a file with an OTRS tag added by an OTRS agent, but wasn't able to do so due to some abuse filter warning. The warning says "You are trying to add a OTRS permission tag to this page. In general, such tags should only be added by OTRS members."
And then it says that "You may press 'Save page' again if you like to save this edit.' But there's no "save page" button, there's only the one that says "Import", and whenever you press it, you get the warning again and again.
Even if you try to "Edit File Info" and temporarily remove the OTRS tag, the warning persists, and doesn't let you import the file.
The only way you could move such a file to Commons seems to be the one when you preliminarily remove the OTRS tag, then press the button to move to Commons, and revert your own edit after the file is imported. But this way is kind of counterproductive.
