As previously documented, celebrities have said some very dumb things on Twitter over the years.
Due to these mistakes, or due to a number of other reasons, many stars out there have attempted to quit various social media services.
Some have succeeded, while others have returned shortly after they vowed to leave.
Here’s a look at various celebrities who, at various times, have simply had it with Twitter and/or Instagram…
Justin Bieber

Click on the above headline to read the complicated, messy situation that led to Bieber deactivating his Instagram account in August of 2016.
Demi Lovato

Demi Lovato left Twitter in way back October 2010, right before she went into rehab. She returned five months later… and then left again in 2012 after going on a Twitter rant about trust. She then returned for a number of years, sharing personal stories about her struggle, only to say goodbye in the summer of 2016 because trolls suck.
Lena Dunham

After getting in some trouble for some inappropriate Tweets, and receiving loads of backlash as a result, Dunham said Twitter was no longer a “safe space” for her. She left the website in late September 2015.
Iggy Azalea

Iggy Azalea does not always “fancy” the social media service. She tweeted on February 18 that she was taking time away from social media because she “[needs] to be happy and it is too negative and draining.” But she has since returned.
Jennifer Love Hewitt

Jennifer Love Hewitt took a break in 2013 due the negativity people choose to send on Twitter, but she returned just a few months later.
Alec Baldwin

Alec Baldwin famously vowed in 2013 he would never reopen his Twitter account after he exploded in a expletive-filled Twitter rant directed at a British reporter. He’s since returned, but not under his former personal account.
Kanye West

Kanye West said goodbye to Twitter in 2012, deleting his old Tweets and unfollowing everyone except his then-girlfriend Kim Kardashian. But he’s now back to talk about Kim, his fashion line and other topics.
Miley Cyrus

Miley Cyrus left Twitter way back in 2009. And again the following year. But she was never able to stay too far away, often returning to show off new, weird photos and messages.
James Franco

James Franco quit Twitter for almost two months in 2011, even predicting the end of social media. But it never happened, not even for Franco. He’s back on.
Chris Brown

Chris Brown twice left Twitter, once after complaining that Walmart and other stores weren’t stocking his album … and another time when he got in a Twitter feud with comedian Jenny Johnson over his on-again, off-again relationship with Rihanna. That was awhile ago. He’s now back.
John Mayer

John Mayer told Rolling Stone back in 2010 that he was quitting Twitter because he “couldn’t have a complete thought anymore” and he turned into a “tweetaholic.” Naturally, he’s also returned.
Nicki Minaj

Nicki Minaj bid farewell to 11 million followers in 2012 after website Nicki Daily reportedly leaked songs from her new album online. But she returned mere days later… and now has more than 18 million followers.
Shia LaBeouf

Shia LaBeouf dropped Twitter after getting bullied by the public. We hope he never returns.
Megan Fox

Megan Fox has quit Twitter on multiple occasions. She posted this photo to Instagram soon after divorcing Brian Austin Green, but she remains relatively silent.
Stephen Amell

Stephen Amell got flak for controversial Tweets surrounding Ahmed Mohamed. He explains his social media absence in this video.
