Question: Provide the name of artists who released at least two bootlegs in 2016.
Evidence: at least two bootlegs refer to COUNT(releaseType = 'bootleg')≥ 2; groupYear = 2016;

SQL:
SELECT artist FROM torrents WHERE groupYear = 2016 AND releaseType LIKE 'bootleg' GROUP BY artist HAVING COUNT(releaseType) > 2
