I repeat: there is no delete key on the Internet
In fact, when it comes to technology, there is no delete key anywhere.
Technology is designed to remember things for a very, very, very long period of time.
If you put something online, through an app on your phone, etc it’s basically out there forever!
Don’t say/do something you’re going to regret. If it’s going to come back and haunt you in the future, don’t do it.
For example, that incriminating photo of you posted on Facebook, well, one of your friends saved a copy of it and is planning to use it on your wedding day…hummm…
