Tumblr decided to spam the idiots of /b/ with WHAT IS AIR and trollface.jpg in hopes of hipsters everywhere becoming the ultimate trolls. /b/, specifically got mad at this and summoned the idiots of anon to come together and DOS tumblr.
Tumblr spammed 4chan. They forgot that 4chan are better trolls than they are. 4chan can hack. Tumblr can’t. 4chan is spamming them with gore and porn while the more computer-savvy members are hacking into Tumblr’s system. I would back up everything that you care about if you have a Tumblr, because I don’t think the site will remain up for much longer.
