Be a good netizen, have good netiquette
We live in a world where the internet has become a big part of our lives. Unfortunately we tend to abuse the freedom the internet has given us. We fail to follow any basic etiquette, to the point that some seem to have never learned these basic ideas.
Be respectful to others: Usually any interaction in real life people try to respectful to others. If we treat others without respect or sincerity, then the other person feels dehumanized, and in return they’ll treat you in the same way. On the internet though, people can leave all sorts of malicious comments, and walk away without any consequence. The internet provides an atmosphere which allows the user to hide behind their screen which allows them to become invisible and invincible.
