Australian pollster Mark Textor has quit Twitter after his posts earned him the ire of the prime minister and reportedly attracted death threats.
The Liberal party strategist made global headlines this week with a series of tweets aimed at senior Indonesian politicians, including President Susilo Bambang Yudhoyono.
"What sort of head of state communicates with a neighbouring government by twitter FFS? That's insensitive," Mr Textor said in one tweet on Tuesday.
In another, he wrote: "Apology demanded from Australia by a bloke who looks like a 1970s Pilipino porn star".
The comments came as anger mounted in Indonesia over claims Australian spies had tapped the mobile phones of Dr Yudhoyono, his wife and confidants in 2009.
Mr Textor later apologised - also via Twitter - and Prime Minister Tony Abbott described the tweets as "tacky".
But by Saturday Mr Textor had deleted his Twitter account.
His handle, @MarkATextor, has been taken over by a user whose biography simply reads "chicken fancier".
Fairfax Media columnist Paul Sheehan has claimed Mr Textor left the social networking platform because he had received death threats.
Mr Sheehan wrote on his own Twitter page: "Mark Textor has quit Twitter. He has no account. `Too many death threats,' he told me today. `Not worth the oxygen. #auspol".
Mr Textor is a co-founder of market research and communications firm CrosbyTextor.
His biography on the firm's website describes him as "the most astute judge of public sentiment in Australia today".
AAP was unable to reach him for comment on Saturday evening.
