# Tumblr Evil Detector

## Description

This is a simple TamperMonkey script that does one thing: warn you if
you're about to reblog a post with a script in it.  Malicious users will
often hide javascript tags in the caption of a photograph which detects
when you're actually looking at the page (through mouse or keyboard
actions) and redirects you a site full of malware, spam, or porn.  This
script is intended to help prevent that, and make your follower's
reading experience more pleasant.

## Installation

You will need Tampermonkey installed in your browser, then install the
Javascript file found in this directory into Tampermonkey.

## Behavior

The URL filter currently only identifies pages on Tumblr that are POST
pages.  If the user has a custom DNS, sadly we can't detect them, but
few if any spammers go to those lengths to snare people.  The current
behavior is that, if a post on the page contains malicious javascript,
that post entry will be decorated with a new border and the footer of
the post will contain a black box with the words "SCRIPT DETECTED."

That's all it does.  It just *tells* you, it doesn't fix anything for
you.  It's very short.  But it's also very effective.
