How about I used to catfish when I was little?
That does not seems okay. Why did you catfish when you were little?
I felt people like kids who looked good and would not ignore them.
It is very wrong to lie to people on the internet. You could be in danger if you ever tried to meet up with these people.
I have changed. I wouldn't do something like that anymore.
Well I am glad that  you have changed. Lying to people is not a good thing to keep doing, it will make it harder for people to trust  you.
