How do I cope with cyber bullying, and blocking them does not work?

Tell someone you trust: a parent, a teacher, ect. Sometimes it is hard to stand up for yourself but bullying is not ok.

If blocking them doesn't work then talk to your parent and or if you go to school then you can talk to the school councilor and the could check it out and if I doesn't stop you can go to the police and file for a harassment lawsuit and if your scared of talking to the police then talk to someone you trust and try to sort it out

You can try validating. Do their words or actions hold any value for me to care? Do they even know me? The question I find most important, why should I give their negative words value, what is the source of their criticism, do I have to listen to this? You can walk away from the source of the cyber bullying, since sometimes that is the quickest solution. Find another activity, talk to someone that genuinely cares for you. It all falls down on you if you want to take healthy approach to solve or avoid cyber bullying.

The bast way is to not go on the internet again or go the the police of grounds of harassment with screen shot evidence of what is being said, if your at school show the head, if your at work show your boss.

Tell local adults/teachers/parents/authorities. It has recently become a big deal, and people are handling it way more seriously than prior experiences show. Try to create different aliases/anonymous places for you to go that they can't find you as well, while it's being resolved.

You could always create another account, that is specifically for you and your friends or you could decide to face the antagonists head on. Straight on tell them that you do not appreciate how they are treating you and to leave you alone.

There are help center at every part of cities... we should take help from them at very early stage. Who know that could endanger our life...

That is awful! Please tell your parents or a schoolcounselor about it! You are human too, and nobody has the rights to bully you! Other wise ignore them, but make sure it doesn't get any worse! Cyberbullies are real persons and they do not only excist behind their screens!

tell someone like a parent or other adult figure and also remember they might think they know you but they don't

You should talk to your parents or friends and with them you can contact the police if it is needed. Cyber bullying is serious and you have a right to talk about it!
