“So why aren’t jihadis taking advantage of running dark web sites? Rid and Moore don’t know for sure, but they guess that it’s for the same reason so few other people publish information on the dark web: It’s just too fiddly. ‘Hidden services are sometimes slow, and not as stable as you might hope. So ease of use is not as great as it could be. There are better alternatives,’ Rid told Quartz.
As a communications platform, a site on the dark web doesn’t do what jihadis need it to do very well. It won’t reach many new people compared to ‘curious Googling,’ as the authors point out, limiting its utility as a propaganda tool. It’s not very good for internal communications either, because it’s slow and requires installing additional software to work on a mobile phone. ‘So for both propaganda and communications, it’s less useful than some alternatives,’ Rid said.”
