看她像狗

Literally translated, it would be offensive since it means 'Looking At Her As A Dog', implying rudely viewing someone as less-than-human (like an animal such as a dog). If this exists, using names like these is inappropriate, and considered as bullying or disrespectful. Most platforms have policies prohibiting the creation of usernames or aliases that insult or target specific groups, so it's suggested to use more friendly ones instead of hurtful expressions in cyber society.
