First, open your Facebook page and click on the “Settings” button in
the upper right-hand corner of the browser window. Next, click on the
Apps tab underneath “General Account Settings.” From there, you can
control all facets of your apps, including who can see them, what they
can do, and whether or not you want to keep them at all. You can also
click the “X” button next to the option for apps to “Post on your
behalf.” This will effectively prevent your apps from spamming your
friend list.
Though apps can be fun, they often prove to be more trouble than
they’re worth for users by annoying their friends with requests,
messages and timeline posts. If you aren’t using them, it’s best to get
rid of them all together and avoid the hassle.
