In one sentence, describe what the following article is about:

Some bullies start out as a friend, an ex, or someone else you know well. If it’s possible to have a reasonable discussion with the person, ask them to stop. Have the conversation in person, not through email or text. Be clear and direct, and say something like, “I saw those things you said about me on Facebook. That’s inappropriate and it hurt my feelings; I’d like you to stop saying those things about me.” If you don’t know who the bully is, or if you’re being bullied by a group of people, attempting to talk it out probably won’t work. If talking it out won’t work, don’t directly respond to the text messages, instant messages, emails or other communications you may have received from the bully. Bullies want to elicit a reaction from their targets, so firing back a text will only make things worse. Your best course of action is simply to disengage. Also, don’t threaten the bully to get back at them. Sending a threatening message out of exasperation will only provoke the bully to keep up the bad behavior, and it may get you in trouble, too. Screenshot or save every email, text, instant message, social-media post, and any other evidence of cyberbullying that you come across. Record the time and date that each message was sent. If you can’t screenshot the offensive messages, you can copy/paste them and save the text on your hard drive.  Having as much information as possible about the bully’s behavior will help you determine how to stop their behavior. You can also show this evidence to an authority figure to prove that you’re being bullied. Immediately put an end to the bully’s ability to harass you online by blocking that person from direct communication with you. Take advantage of social media sites’ privacy settings to make sure the bully can’t engage with you online anymore. Take the following steps to protect yourself:  Delete the person from your email contacts and block instant messaging communication. Delete the person from your social networks and use the online privacy settings to ensure that the person can’t get in contact with you again. Block the person from texting your phone.

Summary:
Ask the bully to stop their behavior. Don’t respond to the bully’s messages. Save the evidence of cyberbullying. Block the bully on all online platforms.
