I think that one of our wisest and most respected contributors, Jack Knave, has had his computer taken over by a malicious WUMbot. Almost all the posts purporting to come from JK's computer now appear to be produced by some non-human random bullshit generator.
This is very worrying - I hope everyone has sufficient malware protection to ensure that their own computers don't also become infected.
I do hope JK can get to the bottom of this problem and that we can see his authentic contributions appearing again.
