One of my prior jobs at Chevron was to monitor layoff.com and plant crazy stores in order to discredit the site. If employees started posting items that hit home really hard or items CVX did not want to discuss, I would start posting crazy topics, profanity, use of crazy words etc.
I would say the majority of the stuff on here about CVX is fairly accurate. You can tell the distraction post by the wording or complete change of subject that has nothing to do with CVX.
Just a helpful hint.
