imagemagick

I had been running out of memory on my server lately and I noticed some individuals uploading the same "file" over and over in quick succession which locks up my instance of mini_magick. Eventually the morgify gets stuck in an infinite look. I've taken care of it by having a daemon watch the morgify process if it get's out of control, but was wondering if there was a better solution enter image description here

You can see the same *.gif being uploading in quick succession. I tried downloading this file too, and it isn't even a gif. I don't know what it is (I can't open it). Anyone experience this kind of exploit before?
