The indieweb IRC channels have a permanent occupant: Loqi, a chat bot.
It does a number of things, among them saying "Good morning", replying to "a or b" questions and taking commands to edit the wiki. And it prints the page title of URLs.
I noticed that it would show the full content of github comment URLs and tried to use that to inject commands:
It turned out that Loqi would not take commands from itself, except countdowns: "$n minutes until $text":
<cweiske> https://github.com/cweiske/test/issues/1#issuecomment-311087678 <Loqi> 2 minutes until boom <Loqi> I added a countdown scheduled for 2017-06-26 8:09am PDT (#6035)
So it is possible for anyone to add countdowns to Loqi without ever talking to it directly :)
