Snapchat gives you the illusion your naughty pic will disappear, but screenshots are forever.
A growing number of people are having photos of their scantily clothed selves shared unwillingly on the internet.
It's being encouraged by trends like the #1fingerselfie - where women take a photo using a single finger to cover their privates.
Many New Zealanders weren't aware of the scale of the problem until the Roastbusters scandal made headlines.
Three years on, there's a new service which makes it easy to report this kind of abuse.
In 2015, the Harmful Digital Communications Act made it illegal for people to post anything online that deliberately causes serious emotional distress. An individual can be fined $50,000 or face two years in jail, while a company can be fined up to $200,000.
The majority of prosecutions so far have been for revenge porn - when a photo or video taken with consent is later shared without permission, often after a break-up or as blackmail.
One man was jailed for sending half naked photos of his ex-girlfriend to a shared work email address. Another was charged for threatening to send nude pictures of his 16-year-old former girlfriend to her mother.
A new NetSafe hotline has had around 500 enquiries in its first two weeks of operation. People can either phone or email the contact centre to report online abuse, and get help removing unwanted material from the internet.
Social media sites can be pretty quick to take things down, however. NetSafe executive director Martin Cocker says it is normally a matter of hours.
"Most of the big social media sites and pornography sites are very responsive to requests to remove revenge porn content.
"People put content onto popular websites to increase the impact, and obscure websites to make it harder to find and remove."
But if your video gets posted on an obscure site, it could take longer before it gets removed because it blends in with the rest of the content.
The safest selfie game is to not have one. Once your photos hit the internet, they could be there forever.
NetSafe's new hotline can help you get the content taken down and create a plan to stay safe online.
If you have been abused online, you can call NetSafe toll free seven days a week on 0508 NETSAFE (0508 6387233).
