I think everyone is guilty of this. We all want to look our best and when there are some anomalies that could expose what we don't want, we crop it. I don't expect anyone to make a picture in an untidy apartment and not change the background before posting on social media.
My opinion has always been never to believe all I see on social media. Many are not real. Besides why show off on social media. It's not compulsory that every fun activity one engaged in with friends or family members must be posted on social media. we just have to be social media smart and live quietly.
