Maintaining Your Privacy on Skype
As with all Internet endeavors, it's vital that you take some steps to maintain your privacy with Skype. In order to keep Skype orderly and free of spam, you'll probably have to block people at some point. Of course, you may also need to block a contact for other reasons. If you just want to lay low for a while, or need to avoid online harassment, Skype blocking can be a good start.
The first step will be to get your privacy settings up-to-date. Skype spam is quite easy to prevent with the proper privacy settings. Start by going to Tools > Options in the Skype toolbar. Look for a tab labeled "Privacy" on the left side, and then click it.
You can choose from a few options. The basics just let you set up different policies for videos, calls and instant messages. There are also useful options for separate privacy issues though. In this setting, you can choose how long you keep your history, whether you want your status to be viewable online and whether Skype can use your info for third-party ads.
You may also have noticed that there's a new sub-tab under privacy, labeled "Blocked Contacts." That's the next step for handling specific contacts.
