Here is my two cents on traffic exchanges.....since I have owned a couple over the years.
Auto surf traffic exchanges are for the most part, not worth the while.
Many years ago, I came across a downloadable free program that was actually a bit tough
to set up at that time. The program would run on autopilot the auto surf traffic exchange.
I was impressed by it and would let it run all night while I slept. I told some others about
it and we were all gaining a lot of credits. However, one little issue we had was that it would
surf right on thru virus pages and everything under the sun. In addition, we never, none of
us, saw it the least bit worthy. Of course, what we were really doing is cheating the traffic
exchange. Back then, almost everything was a go. I think we were more amazed at it's
operation than we were gaining surf credits.
When people use auto surf's and do as you said 'hydig', they are in essence cheating the
exchange and all the members therein. The purpose of a traffic exchange is like what we
did when I was in grade school in the 60's. We had sort of a trade day in the classroom.
I tell you my story, you listen, then you tell me your story, and I listen.
So when you minimize that window, and you're not watching it, you're cheating everyone
at that exchange. Someone either spent their money to buy credits or they spent their
time to achieve credits in order for members to view their page. What if everyone minimized
the surf page? HaHa!
Therefore, what you have touched upon in your post 'hyidig' is called 'marketing ethics'.
That is a very big problem in the online business world.....people not using ethics and
treating others as they would like to be treated.
