Opposition environment spokesman Greg Hunt's office denies it is responsible for an army of fake spam Twitter accounts that social media experts say retweeted his post and other anti-Labor missives.

The spambot claims first appeared on Sunday in a Storify document that quickly spread, and appeared to be backed up after Twitter disabled several of the alleged “bot” accounts referred to.

Shadow Minister for Environment, Climate action and Heritage Greg Hunt.

The suspicious retweets were on Mr Hunt's tweet from last week that claimed the carbon tax was partly responsible for job losses at Penrice Soda in Adelaide. It has had over 200 retweets compared to the single digit retweets his other posts get.

Mr Hunt's chief of staff Wendy Black said “we know absolutely nothing about” the spam bot profiles. Hunt also denied any involvement this morning on Twitter.
