With so many opinions being shared on social media, disagreements are inevitable.
If you see something or receive a message that you don’t like, try to keep things respectful. Quote facts to correct misinterpretations, or ignore the post and unfollow the user if necessary.
Trolling is where someone seeks to provoke a negative response from others online.
What distinguishes trolls from those who are simply criticising or disagreeing with you is that they don’t really want to persuade you or engage with your opinion. They just want a negative reaction.
Don’t feed the trolls. Most of the time they will go away if you don’t give them your time or attention.
If you do want to respond – for example, to correct the record if someone has said something untrue about you - try to take as neutral a tone as possible.
If you're finding messages from someone upsetting or distracting, you can mute or block their account.
You can also report posts that are harassment, threats or spam. Information on when and how to do this is covered in Twitter and Facebook's Help Centres.
It's illegal to threaten or harass someone online. The police should take it seriously if you report it. Citizens' Advice Bureau has some useful information about harassment and your rights.
