Some of these aren’t really cheating. “Stealing signs” is normal, even expected, play, so long as it’s on the field of play. Using electronics, etc… does cross the line and should be banned/punished.
Steriods, until made illegal, wasn’t cheating as it was not only legal, but tacitly encouraged by the owners and management of MLB who loved the gaudy offensive #s and the increased attendance that correlated with that. People focus their ire on Clemens, Bonds, etc… but Selig is just as guilty, if not more so.
Doctoring equipment is the more legitimate charge here. Players have altered bats and balls since the game began… which is largely why there are regulations and controls around them now. Corking, though, has largely fallen out of favor as detection is not that difficult and the benefits are debatable.
Definitely a colorful history.
