You don't want to be bullied of course, who does. But... You must see the problem there?
And yes, usually the best reaction to a bully is to refuse to be bullied but you are perpetuating this and you aren't accomplishing anything. Person IRL bullying you? Put a stop to it by making it more difficult then the bully can handle.... that may cause some temporary hardship on you but it won't be long before he/she will move on to an easier target.
Stranger online being an ***? Easy solution. Ignore it.
