Online bookmaker Sportsbet has come under fire for offering odds on the legalization of same-sex marriage in Australia.

ABC.net.au reported that Sportsbet has withdrawn its postal survey on Australia’s same-sex marriage from the market after drawing flak on social media and prominent Yes campaigner and Sydney MP Alex Greenwich.

The Australian bookmaker ran advertisements related to the same-sex marriage postal survey on various platforms including Twitter and Instagram. Their campaign, according to the report, dates back five years ago, checking the public pulse on how Australians will cast their votes on the issue.

Sportsbet’s campaign, however, ended last Wednesday evening after it informed punters that it will no longer accept bets on the issue.
