Stay away from 'CrashSafari'
When anyone says to you 'MATE! Click this link immediately! It's amazing!', you should be wary. Messages that say things like this either take you to an annoying joke, or something wildly inappropriate, like a RickRoll or some mucky video (we'll let you decide which is which - you might think Rick Astley is the dirtiest thing you can send a person for all we know).
Anyway, there's a new one doing the rounds, called 'CrashSafari'.
Basically, if anyone links you to it, it makes your iPhone crash, overheats it, and generally gives you a pain in the neck. Android phones aren't too fond of it either. Desktops? Yep. They struggle with it too.
In short, when you click the link, it takes you somewhere that generates a huge, and increasing string of characters, which briefly buggers up your device.
Of course, with TinyURL, Bit.ly, and the like, people are shortening the links in a bid to disguise their japes.
If you've been reading this and think 'Ha! I'm exactly the kind of person who likes to play pranks like this!', then you need to copy the following URL and send it to someone else. http://crashsafari.com/ If you clicked it, you can't say you weren't warned. If you have an add-on or whatever, that allows you to pre-block sites, feel free to add this now.
