But that's exactly the problem, Simon - because he said he did it, doesn't make it so.
Read the 'Veracity of claims' section in the Wiki page along with the what the Universities also say.
Add to that the fact that Google now include this disclaimer, "...nor does it lay claim to the validity of the actions described herein".
If you actually look at the c....s he did, as opposed to those he said he did, you'll see that those that suffered were small businesses and individuals.
Honestly, it's hard to think of a person more deserving of the title "low-life scum".
