I dunno about that...I mean, I usually play on this one parkour server, and the people can get so feisty on there that you feel like you gotta hide in a corner all day...I just don't know what to do!
its a good idea to try to hold it in, but most of the time, that's not possible! Also, whenever I tell them to stop cyberbullying, they just say, "WOW NOOB."
then they deny that they are cyberbullying. Also, I have a few methods for handling cyberbullying in mc such as-->
bully: "wow [insert name here] you suck"
you: "I know right"
that method is good cuz the bully just wants to make you mad, but your bassacily telling them that you are the happiest person on earth! Also if anyone is reading this that ever said "noob" to someone on mc, then please, PLEASE just stop...it's really rude and mc is just for fun... 
Thanks...anyways, just I may need some help! 😶

"All I'm trying to do is get out a clear and simple message: If you're mad at someone, try to hold it in."

I understand what point you were trying to get across, but that's really the opposite of what you should do... There's a huge difference between cyberbullying and trying to talk it out with someone when you're angry. It's like the difference between "your blogs suck" and "this is a good start, but you might want to consider fleshing out your ideas more and trying to write longer blogs".

This is on the pop reel? ...

If you can't handle bullying on the internet... I don't even know what to say to you.

Cyber bulling in my opinion is a load of bullsh*t. If you aren't old enough to understand and accept that people aren't going to be nice on the internet, you shouldn't be on it. You usually don't know the person and they don't know you, so why would you care? If it does affect you, get off the internet
