I love to catfish people.
Why do you enjoy something so cruel?
Because it's funny to see the victims reactions when they find out.
That's a pretty antisocial activity!  Deceiving others, especially just for fun, is wrong.  Think about how they feel!
That's what they got for being stupid. If you're dumb, people will take advantage of you.
Just because you are able to deceive someone, doesn't mean you should do it. You are playing with the feelings and emotions of other people for your own amusement which is wrong. How would you feel if someone did it to you?
