Of all the websites, one that has attracted attention recently is myspace, com. Most of th

is attention has come from the media and tells every reason 【B1】______ the website should be 【B2】______ The threat of Internet predators (窃掠者) is indeed a tough reality,【B3】______ shutting down the site is not the answer. If myspace, com 【B4】______ shut down, another site would quickly 【B5】______ its place. Therefore, the right way is to teach teens how to use the site safely and educate them 【B6】______ who may be predators and how to 【B7】______ them.

The key to 【B8】______ safe on the Internet is to make sure that your profile (个人资料) is secure. The 【B9】______ way is to change the privacy setting on your profile to "private", which protects your information 【B10】______ only the people on your friend list can view it. Although this is【B11】______ , it is not perfect. Predators can find ways to view your profile if they really want to, 【B12】______ through backing in (黑客入侵) or figuring out their way onto your friend list. Thus, you should never post too much personal 【B13】______ Some people actually post their home and school addresses, date to birth, and so on, often 【B14】______ predators know exactly where they will by and 【B15】______ .

The most information that is safe is your first name and province. Anything more is basically 【B16】______ a predator into your life.

Another big problem is photos. I suggest 【B17】______ skipping photos and never posting a photo of a friend online without his or her 【B18】______ .

Most important, never,【B19】______ any circumstances, agree to a real-life meeting with anyone you meet online, 【B20】______ how well you think you know this person. There are no guarantees that they have told the truth.
