Just to be safe, can you explain the exact policy on this?

Most definitely, and thanks for asking. The policy is very simple ...

The only URL you are allowed to promote via "auto surf" or "rotator" programs, or any other automated means, is your Referral URL that is used to refer new users to the TrafficSwarm.com website.

You may NOT use them to promote your Start Page or any other URLs - because it wastes other users' hard-earned credits and we can't have that.

Any user who promotes anything other than their Referral URL via these types of programs will find their account automated deleted.
