Have you noticed that sometimes when you search a name in Facebook it appears in “People You May Know” in your stream? Well, your profile could also be recommended on that person’s page! Go incognito.
Here’s how to avoid that.
Search Facebook through the Chrome browser.
View the profile without alerting the Facebook algorithms.
If you sign in, your account can be exposed. Incognito mode provides limited information. The alternative is to sign out of your primary account and establish a research one, but don’t impersonate a real person!
Does the incognito window prevent notification since you still have to sign into FB to see more than the front page of the profile?
