I think that’s a little defeatist. While sites like this will always be able to exist as tor hidden services or whatever, being available over https with a normal domain name massively increases the reach these sites have. Furthermore, there’s a big element of “performing for an audience” that these shooters tend to have, given the posted manifestos that include community in-jokes, so the reach that a site has makes it much more appealing for mass shooters.
