If you've received a campaign text or call in the last few months, you're not alone.

The ABC has received more than 140 contributions, comments and questions about the unsolicited texts through the You Ask We Answer and Hidden Campaign projects.

Rosie from the New South Wales Riverina, who did not want her surname published, said she has had enough.

"I'm currently being bombarded by texts from the Palmer United Party [sic], and the content seems to be targeting me specifically as a rural resident," she said.

"I've never knowingly or willingly provided my details for that party, but I want to know how they've obtained it and how they've identified me as living in regional Australia.

"What I find really offensive is that I can't block or opt out of these texts, because the number that sends them is obscure.

"I just find that tactic very predatory and very intrusive, and I find them very unsolicited and unwelcome."

Ironically, Clive Palmer has promised to abolish the ability of political parties to send unsolicited texts if his United Australia Party wins government.

But given the major parties both use the tactic themselves it's unlikely to cease any time soon.

The Coalition is still haunted by the effectiveness of Labor's 'Mediscare' campaign in the 2016 election, but they too are running a scare campaign on death taxes.

How did they get my number?

Bulk text messages and calls are cheap, and there's a chance the numbers were auto generated and you were simply unlucky enough to turn up on the database.

But Rob Nicholls, a University of NSW telecommunications expert, says it was also likely the parties got your number online — and that may not be all they have.

"They have the electoral roll, White Pages and everything that you ever put on Facebook to identify you," he said.

That allows political parties to build, or in part purchase, a database to target their messages, particularly geographically.

Can I opt out?

Mr Nicholls said while there will be an "avalanche" of texts and calls in the last week of the campaign, there was not much you can do to stop it.

Political parties are exempt from the Do Not Call Register and blocking numbers is difficult because they often change.

"I'm afraid the answer is just hang up," Mr Nicholls said.

"I know that's not very helpful advice because the annoying thing is you have to get there before you realise it's only a political party calling and not an important call."

There are some rules around when calls can be made and texts sent, with a ban before 9:00am any day, after 5:00pm on the weekend and after 8:30pm on a weekday.

But there is nowhere to make a complaint if there is a breach.

"What you can do is to contact the local office from the party that you're getting the text from and ask them to stop, but the problem is they're not obliged to stop," Mr Nicholls said.

The ABC asked a number of political parties how many complaints they received about unsolicited texts and calls but none responded.

The Australian Communications and Media Authority only takes complaints about commercial texts and calls, while the Australian Electoral Commission is only interested in the authorisation of political correspondence.

So if you've had enough of the calls and texts, the best advice is to just ignore them.
