In the circle of friends, what is the mentality of people who curse in space?

Some people swear in the circle of friends, never name names, and always start with "someone" and end with "someone". In addition to negative energy, such people are also timid. If you have problems with others, don't dare to ask them in person, don't solve problems through communication, and go to a circle of friends to curse. However, they blocked the target, but dumped the garbage to other people in the circle of friends, polluting the air in the whole circle of friends. Some people say, my circle of friends, how I want to vent is my business. Negative energy is contagious, and the circle of friends who curse all day affects others' mood. This behavior is disgusting. In this society, everyone has pressure that others can't see. No one has the obligation to be a trash can for your bad mood. Please shield them, keep your distance from them in reality and don't let them infect you with negative energy!
