Still, there are people on Facebook who do not properly use their names. Who knows why! Back in 2011-2012, it was normal for me to see friends with different names on Facebook; there were no cringes. Time has flown rapidly and things have changed eagerly, we outgrew the trend and considered it out of style.
But what should you do whenever you encounter someone on Facebook with the same instance? Respect the person. No matter how it makes you cringe with disgust to see that “Bhozxs *Insert Name*”, you should be able to detect the person’s existence; he is a human being and he has feelings too. If it’s making you uncomfortable, approach him politely and kindly, and tell him about what you think.
On the other way around, it is preferable to use your real name on Facebook. Why? For the efficiency of pinpointing one’s identity, and for the efficiency of finding a specific person’s official account on Facebook.
