Does Nash worry about what he posts online?

Let's just face it: It seems like Nash Grier has, like, no filter at all! That's why the M Editors were shocked to find out that the vine star does think twice before posting stuff online and he wants fans to do the same. "Whatever you put on the internet or through text messages, anything you put in a digital space, is there forever," Nash advises. "All of your memories online will be forever, but so will your mistakes, so you've got to be very careful with what you put on there." He's right: It's best to stick to non offensive posts, like the hilarious video Nash posted of him crying over the news that Zayn left 1D!
