Some one was bound to ask for proof. Unfortunately i no longer have the specific details but I am in the same boat where tomshardware was the first place to go for hardware news.
The story
i was in the marked for video cards and started looking at their reviews and discovered inconsistencies in their frame rate numbers. On closer investigation it appeared certain brands had higher rates even when using the exact same VPU.
Strange . . so i went hunting for other reviews and found no less than 3 showing approximately the same rates but all were lower than on tomshardware.
Closer inspection of the article at the time showed a greater of manufacturer specific advertising links in that one article than in others. . . . hmmmmm i smelled something bad.
I attempted to contact them via email several times pointing out inconsistencies and never received a satisfactory answer just denial.
AFIAK being paid by the manufacturer to review their product is the same as advertising and full of extensions of the truth. Since then i have never trusted their reviews.
EDIT: Oh and i have noticed they recently publishing an article describing the testing methodology in detail.. . . I wonder if they were becoming aware of the loss of faith in their reviews. Did this hurt their bottom line? Hmm
