On December 26th and 27th, 2014, an anonymous person/s has gone into tumblr's tags to locate people within the Supernatural fandom who have struggled with depression and anxiety, sending them hateful messages telling them to harm themselves and commit suicide. This has happened on a massive level, with hundreds of blogs affected. These hate attacks have lead to deaths, attempted suicides, severe self harm, and emotional trauma fandom-wide.

Within the coding of tumblr, the ip adresses for messages are stored, even for anonymous messengers. Go into the code. Find the people responsible for this and work with the police and internet service providers to identify these people so that they can go to jail for these crimes. These people should never be allowed to access Tumblr or any site where they can perform this kind of hatred again. 

As of December 28th, the hate has expanded to even more fandoms beyond the Supernatural fandom. The number of anonymous people/persons appears to be growing, as the attention to detail and the sheer number of messages sent has reached a staggering level. This needs to stop, now more than ever.
