Social networks are a great way to stay connected with family and friends, enabling us to keep up-to-date with what’s going on, or perhaps the latest holiday snaps.

There are a vast number of social networks – or social media – to choose from now, but the leaders are Facebook, Twitter and Instagram.

While they can be a fun and enjoyable escape, unfortunately the experience can be blighted by people who set out to upset others.  Whether it’s abuse from someone you know, or someone you’d just prefer not to associate with, there is always a way to carry on using social networks without them ruining it for you. You can block them.

Blocking is also a way of controlling your privacy – you may not want your boss or an ex-partner looking through your feed.
