There are calls for an independent review into the use of social media among Tasmanian ministerial staff, with Labor raising questions about a Facebook account that targeted poker machine opponents — which vanished soon after the election.

The account, under the name Brent Smith, began commenting on the Facebook page of a North Hobart pub run by Brendon Garland in early January, writing a poor review of his venue shortly after the hotel shared an anti-pokies Facebook post.

Mr Garland said he was "positive" the account was a fake and was trolling him for political reasons.

"I think a lot of people would understand when you look at a Facebook profile, you can tell if they're fake or not — you know, they've got no friends," he said.

"We had a good look at the profile itself and none of it makes sense."

Mr Garland said after that, family members showed him similar comments by Brent Smith on the Facebook page of an anti-pokies campaign group.

"He was just trolling that every day, every night. And not just that but he was trolling other Facebook profiles."

A senior advisor to Premier Will Hodgman, Martine Haley, was forced to quit this week after it was revealed she had used a fake Facebook account to target a woman who'd been critical of the Liberals' abortion policy.

The account, and an email address under the alias Alice Wood-Jones, was used to send photos of the woman's comments on Twitter to her employer. Another Liberal staffer interacted with the fake account used by Ms Haley.

Tasmanian Labor put itself offside with many in the hospitality industry in December after it released its election commitment to strip poker machines from pubs and club venues by 2023 — a move which sparked a widespread campaign of pushback and claims of job losses should the plan be implemented.

Deputy Labor leader Michelle O'Byrne said it was "unbelievable" that just one Liberal staffer knew about the account, despite the Premier maintaining that it was an isolated incident.

She said it was likely no coincidence that "prominent troll accounts have recently disappeared" and said she was aware of "a fake account called Brent Smith relentlessly trolling anti-pokies pubs and supporters".

Ms O'Byrne said it was implausible that there'd been no discussion of it in the Premier's office.

"This is part of a culture that has been allowed to occur ... we want to understand exactly how many people were involved with trolling and what sort of activities they had," she said.

"Clearly the Government and the Premier's office are embarrassed that they've been caught out, and they should be embarrassed. "

She called for a full and independent investigation to be launched.

Tom Lynch from the Community and Public Services Union said a public servant doing the same thing would have faced more scrutiny.

"There would be a very serious investigation, an independent investigation by the head of agency," he said.

The Premier's office did not respond to detailed questions.

Senior Liberal's dim view of trolls

Former federal Liberal MP and senior vice president of the Tasmanian party, Brett Whiteley, said using fake social media accounts was unacceptable behaviour.

"You can't hide behind a fake name to open a bank account or to enrol to vote. They are criminal offences," he said.

"If I went and screamed some of the discourse that's on social media in a public square, I'd be up for criminal charges.

"And it should be the same on social media, across the board people should not be permitted to hide behind social media fake names."

Mr Whiteley said social media trolling was a widespread problem, not just in the political sphere.

"It's happening in the union context, it's happening in the normal day-to-day community," he said.

Despite its common occurrence, Mr Whiteley said there was "no excuse" for behaviour like that by Ms Haley.

"There's isolated cases of errors of judgement and misdemeanours in every sector of our community. This is something that is very unfortunate, I understand the person in question has apologised for it."
