2019 NHBB Online
The 2019 "NHBB" Discord Tournament was an online history bee-style tournament held during April 2019 on Discord servers. The brainchild of 8th grade Laurel Springs NHB player Ameya Singh, the tournament was won by Sam Brochin. Though admittedly not affiliated with neither NHBB or International Academic Competitions (IAC), the event attracted controversy after it was revealed that a number of questions it used were more or less plagiarized from quizDB and/or past NHBB events.
Aftermath and "scandal"
As documented on this thread, after the tournament's preliminary stages had concluded and packets had been uploaded online, numerous members of the QB community pointed out that many of the tossups used in the tournament were either copied from, or very similar to, questions used in past tournaments written and copyrighted by other quizbowl organizations. The tournament had claimed to be a housewrite.
Fortunately, Singh later apologized for his errors.
