Splogs and the clutter of pop-ups
It’s interesting to note that almost all splogs use Javascript. The reason for this is that Javascript allows sploggers to embed their site with instructions that will increase their “revenue” from all visitors.
For example, they input Javascript instructions for generating pop-up windows when you enter the site or when you click on a link. These windows open up even when you leave the site. Regardless on what triggers the pop-ups, these are one of the most annoying things you will see on the internet and it goes to show how poorly sploggers treat internet visitors when they don’t care if you have a horrendous experience on their site just as long as they earn money doing so.
