Imgur is being used to create a botnet and DDOS 8Chan

Here is the thread where it was first discovered

This is the image OP posted explaining what he found

When an Imgur image is loaded from /r/4chan, imgur loads a bunch of images from 4chan's content delivery network or 8chan (unclear at this point, might be both), which causes a DDoS to those sites.

See this picture: http://ift.tt/1V725E3

You should only see one image loaded in that list, not all of those.

(This what a normal Imgur image looks like when it is loaded http://ift.tt/1KIT1DR. See that only the one image is loaded, not 500 random ones. The injected.js is just a chrome extension.)

Basically, clicking on a Imgur link on /r/4chan ends up opening ~500 links from 4chan.org/8chan.

Looks like imgur is addressing the issue. https://twitter.com/imgur/status/646109824342593536
