I'm running Ubuntu 18.04 and need a foolproof way to permanently block Tumblr blogs from being accessed on my system. Browser extensions such as Blocksite arent effective even when using 'wildcards' such as *.tumblr.com
Elsewhere, I have seen an (outdated) suggestion to block static.tumblr.com and 78.media.tumblr.com, but this no longer works against Tumblr at time of writing, i.e. even with these domains blocked, I can browse a given Tumblr blog without interruptions.
