Before shifting some of its focus to Diaspora, much of IS's efforts were focused on Twitter. But in the past week, the site has been pro-active in removing the accounts of IS members and supporters.
It has since widened that scope to include any member who shares graphic images of video relating to the killing of US photojournalist James Foley.
However, Diaspora, due to its nature, will be unable to take similar action. It is therefore unsurprising that IS would turn to the network, argued Jamie Bartlett, author of The Dark Net, a book looking at hidden internet services and decentralised social networks.
"Not a great deal can be done," he told the BBC.
"In terms of the base technology, decentralised services are incredibly difficult for police to get a handle on. Every time they're clamped down on - the services get a bit smarter, a bit better at evading detection.
"It's absolutely inevitable that organisations like IS are going to be among the early adopters of this sort of innovation."
