> Matt Cutts (when he was at Google) had no incentive to lie to anyone
Umm. Yes, he had a paycheck and bonus package as incentive. Performance reviews too.
But as to Walter's attacking on Cutts, that's just someone not willing to put in the work to being a responsible adult. When it comes to Google search, you can't accidentally hurt yourself/your-site unless you're a bull in a China shop. Also, Google's search is really complicated and I can't generalize for his specific situation but it's extremely likely that it was OP's fault for using 'black hat' techniques (either directly or indirectly).
