The Dallas Mavericks owner Mark Cuban found himself trending on Twitter during Game 7 of the Eastern Conference Finals.

Cuban took to Twitter to ask his 8.8 million followers about illegal streaming.

“Got a personal question for everyone watching heats vs celts right now,” he wrote. “Who is watching on a pirated stream. I’m curious how prevalent it is.”

Billionaire also reposted a poll by another Twitter user that asked: “pirated stream” or “not pirated stream.”
