Just curious what is jingling? It is my first time to hear this word.
Jingling is a chinese software that make hits on any website.. For free ofc.
Better said, you trade traffic with other people that are currently using it. If you use it on your home computer you probably will get a network overload.
Nothing is for free...
Jingling traffics seems more stable and reliable because some of the visitors to your page can give you a click and truly you can get your computer overload by using it.
