People on social media know how to harm others' feelings, which is why they advise caution when posting on social media, as favorable feedback is not always forthcoming. Some comments may be hurtful because some individuals do not care about others' feelings. But people don't listen as they continue to share their business on social media, and you can't blame them because people get excited and end up sharing their business on social media because they want to encourage people when they post their success on social media, but instead they will make fun of you.
