DO NOT DO THIS. Even if your message is anonymous on Tumblr, it can easily be traced back to you by law enforcement. Bite Back already exists specifically to publish underground actions and has a PGP key available for added safety. There are steps you must take to protect your identity - posting about it on Tumblr is foolish and incriminating.
NEVER talk about illegal actions on a computer or account that is connected to you in any way - if you have ever logged into your Facebook, email, Twitter, etc. on that computer, DON’T WRITE A COMMUNIQUE ON IT. If you are at a public library and have logged into the computer with a user ID and password that is connected to your library card or any identification, DON’T WRITE A COMMUNIQUE ON IT. These are obvious things that people should avoid and you are posing a huge risk to yourself automatically every time you talk about it on the internet.

And to whoever runs this ALF Tumblr: assuming you aren’t a Fed or a snitch, which is definitely not something we can safely assume, stop asking activists to incriminate themselves. Just STOP. This is the second time I have spoken of this in regards to your Tumblr page, and the fact that you ignored it and asked people to send it communiques makes you look really suspicious or really, really stupid.
Please reblog before anyone is dumb enough to do this.
