Canseco has led a controversial life in the spotlight after leaving baseball, including stints on reality television shows The Surreal Life and Celebrity Apprentice, and a string of celebrity boxing matches—one of which saw Canseco sued for breech of contract after he attempted to substitute his twin brother for himself in the ring.

Some suspect that the strange social media posts presented by Canseco most recently could be part of an attempt to market himself, since the day after posting the initial tweets he began advertising the opportunity to “hang out” with him, play golf, and "learn about aliens and time traveling."
