Has anyone taken up on this offer? Costs $17 and you can earn $542 a year. You have to reset up your Clixsense membership. You have to change your sponsor and clear your cookies. Sounds confusing and like a bunch of "whoee" to me! Anyone ever join this?

It is obviously a fishing offer, as changing the sponsor is not allowed on ClixSense.
There are several breaking ClixSense' rules and everyone get this offer can report it to our administration!

why would u want to change?

Don't fall for such "teams" because only the person who starts the team and the first 3-4 members who join, end up really benefiting from the promised $500+ per year because the entire team is below them. Those that join later end up getting just 1-2 upgraded referrals.
That $500 promise is just a way to lure members into the team for their own benefit.

You can make that much without referrals if you try hard enough. These so called "teams" are all schemes. So are the "buy active referrals" sites. The phrase "Let the buyer beware" applies perfectly for schemes like those.

Stupid "ponzi" schemes!
