Hi,
I do not think that who receives aggression can be blamed for it. In the case of online bullying, sometimes you can stop it by not paying attention to the bully, but sometimes it does not work that way and you have to fill a complaint. Of course, one can set some goals for oneself for the future, try to analyze one's reactions, so we can get a better outcome next time (if this is possible). But, there is not justification for a bully. And, sometimes we cannot control things, even with 100 per cent effort. You can do your best, be prepared, improve, but, there are a bunch of guys out of there that want to bother people.
