Investment

A large number of autosurfs are investment autosurfs: to earn money surfing, members must pay a fee and are then promised a certain return on their fee. The "investment" is claimed to be a membership or upgraded membership fee and the "return", a per-site commission. In the case of investment autosurfs, members either pay a fee to join and/or to upgrade their account level. This fee can usually vary from a few cents to thousands of dollars, and the minimum and maximum is set by the site operator. The program then offers a commission based on the member's account level for viewing a minimum number of sites, for example, for a period of X days, every day that the member views Y sites, Z% of the upgrade fee will be credited and can be withdrawn from the site. The product of Z% and X is always over 100% to ensure that the member makes a profit. Members also have even more incentive to build a downline because further commissions are received based on the amount of money that referred members put in or earn. The investment autosurf concept is against PayPal's Acceptable Use Policy. Historically, Paypal has blocked most autosurf programs' accounts.

Blog

A blog is a website where entries are written in chronological order and displayed in reverse chronological order. "Blog" can also be used as a verb, meaning to maintain or add content to a blog. Blogs provide commentary or news on a particular subject such as food, politics, or local news; some function as more personal online diaries. A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs. Most blogs are primarily textual, although some focus on art (artlog), photographs (photoblog), sketchblog, videos (vlog), music (MP3 blog), or audio (podcasting), and are part of a wider network of social media. In May 2007, blog search engine Technorati was tracking more than 71 million blogs.
