the bot "Ubuntu QA Website" keeps modifying bugs that are not Ubuntu bugs

[Robert Collins]

See for instance https://bugs.launchpad.net/launchpad/+bug/10
arguably https://bugs.launchpad.net/baltix/+bug/1
https://bugs.launchpad.net/launchpad/+bug/151528
https://bugs.launchpad.net/launchpad/+bug/1894

and plenty of others

I suggest that there should be a whitelist or some other mechanism to prevent bad data input causing this to add spurious tags and comments on other projects bugs.

These are caused by users tagging bugs on there reports -- clearly the bugs cited are spurious, but the bot doesn't know that. It just tags anything entered in on the tracker. It's probably simpler to remove the spurious results on the tracker than it is to control the bot.

We should be able to do more on this once we track down the source of the scripts -- it's been a little lost to time.
