As part of its ongoing campaign to disrupt the Islamic State group's online activities, members of the hacktivist group Anonymous have launched the "ISIS Trolling Day" that aims to make a mockery of the extremist group by posting unflattering images on social media to undermine its credibility.

Announced earlier this week, the campaign is set to run throughout Friday, Dec. 11, in what the hacktivist group described as a "day of rage" against the terrorists. Already members of Anonymous have posted hundreds of images mocking ISIS, with most portraying imagery related to animals such as goats, pigs and ducks. Images have been posted on Twitter, Facebook and Instagram.

"We will mock them for the idiots they are," Anonymous said in a statement on Monday. "We will show them for what they really are -- they do not stand for a religion, they do not stand for a god, they are brainwashers teaching from the young to the old their propaganda against the 'west' when in reality they are just increasing the distance between countries by giving many a bad name."

Anonymous is urging the use of the hashtags #Daesh and #Daeshbags in reference to the term the militant group hates being called. Daesh is an Arabic word, which can be an insult, and ISIS has threatened “to cut the tongue of anyone who publicly used the acronym Daesh, instead of referring to the group by its full name,” the Associated Press wrote in September 2014.

Here are some examples of the images posted online as part of the campaign:

It is unclear if Anonymous' campaign will have any effect and some within the group have expressed doubts about the ability of the effort to make any sort of impact on the terrorist group. In the wake of the Paris attacks last month, Anonymous has stepped up its campaign against ISIS, "vowing to hunt down" the extremist group as part of Operation ISIS or #OpISIS -- a wider campaign that has been seeking to disrupt the terrorist group's online communications since earlier this year. Some have, however, criticized Anonymous' approach to tackling ISIS, with critics saying that taking ISIS-related accounts offline is hindering counterintelligence operations.

To try and get as many people involved in the effort on Friday, Anonymous has published a guide for those looking to troll ISIS, giving users ideas of what to post on Twitter, Facebook, Instagram and YouTube. The full list of the instructions include posting images of goats and referring to the wives of ISIS fighters using the hashtags mentioned above and posting images of dead ISIS members.
