Kitty Flanagan has lashed out at Viagogo over the way in which they obtained tickets to her upcoming Melbourne International Comedy Festival performances and marketed them.

The high-profile comedian took to social media earlier this week to protest the ticket-reseller buying Google Ad Words under her name.

The tactic means people searching for tickets to Flanagan's upcoming performances will be presented with a link to Viagogo's website, despite the company not being an authorised partner of the Melbourne Comedy Festival.

"Please do not get scammed," Flanagan wrote. "Viagogo are ticket scalpers. The tix... are stupidly priced and will not be honoured by the venues I'm playing [at]."
