I did read your post. All it indicated was that YOU weren't benefiting from the surveys. Then you called for WGT to remove them from the site.
If you had taken the time to read the many threads about the surveys before posting yet another one you would have known that people were benefiting from them. It's a love - hate relationship. People either love them or hate them.
Rather than calling for a ban based on one person (you) having a bad experience, why not just ask if anyone else was actually getting through the surveys and getting credits? Ask if there is some trick to it?
Personally, I answer the questions truthfully. I am fortunate to belong to a demographic that is in relatively high demand from the survey companies so I get to complete quite a few.
Other people guess at what the survey companies are looking for and complete them that way. I don't like that approach because it skews the results. Eventually they will quit offering surveys here if the results can't be trusted.
