-- Quidditch Through the Ages (QA5)
After a match against the Appleby Arrows in 1814, the Bangers attempted to capture a Hebridean Black dragon as their team mascot. Their foolishness led to their being banned from playing ever again (QA5).
The Banchory Bangers were known for their "post-match parties" (QA5). This one getting so out of hand must have been the last straw for the Ministry authorities.
