Somebody PM'd me on Twitter this morning, wanting my opinion on whether a document from GCHQ was valid or not. Somebody posted it on B's feed on the 23d but it's really hard to find the original. The person who PM'd me is still looking for it; I'll go look when I have a minute. Which is rare.
In the meantime, I'm posting this image; it's a screen shot of a screen shot. The quality is not the best, which is why I'm looking for the original uploaded image - to avoid the quality degradation that's setting in. Hopefully some of this is readable until I can find the original. Sorry for the low quality but for the moment it's what I have.
