Indian-based mining giant Adani sent out a tweet for World Earth Day late on Thursday evening asking people what they'd be doing to contribute.
The answer, it seems, is mercilessly taking the piss out of Adani.
The tweet was a little ironic because Adani wants to build a massive coal mine in Queensland's Galilee basin.
Scientists say this mine would have a terrible effect on the Great Barrier Reef, one of the seven wonders of the natural world.
And it's really bad timing, because just this week researchers revealed that 93% of the reef has been affected by an unprecedented coral bleaching event.
So as soon as the tweet was sent....
People went in.
And over on Facebook it was a similar situation.
A few Greens politicians got in on the act.
This is your daily reminder: Never tweet.
Happy World Earth Day!
