BEIJING (Reuters) - Alibaba founder Jack Ma's absence from public view in the past two months, including missing the final episode of a TV show on which he was to appear as a judge, has fueled social media speculation over his whereabouts amid a Chinese regulatory clampdown on his sprawling business empire.

China's highest-profile entrepreneur has not appeared in a public setting since a late October forum in Shanghai where he blasted China's regulatory system in a speech that put him on a collision course with officials, resulting in the suspension of a $37 billion IPO of Alibaba's Ant Group fintech arm.
