“If you say something online, it has a different kind of permanence,” Ms. Papacharissi cautioned. “It’s always there to haunt you.”
So over the last two months, I decided to do something different by trying to erase that permanence. Specifically, I used web tools to eradicate the vast majority of my Facebook and Twitter posts. Those turned out to be impractical and tedious to use — though automated, the programs were flawed and missed many posts after several attempts. The chore took about five hours, spread out over weeks.
While I walked away from the ashes of my digital self feeling less haunted, I confess my methods may not be worth the trouble, though there are other, more practical solutions. Yet cleaning up your timeline is an exercise I recommend in moderation if you care about your privacy.
Here’s how I did it — and what I learned.
Testing the Cleaners
Since Facebook and Twitter offer no simple method for doing a mass purging of timelines, you will likely have to rely on third-party tools. I picked two well-reviewed programs: TweetDelete for cleaning up my Twitter account and Social Book Post Manager for handling my Facebook account.
TweetDelete was simple to put to work. It’s a web app you install by visiting the tool’s website, tweetdelete.net, and authorizing the application to connect with your Twitter account.
From there, you can choose to delete tweets that are more than a week old. The app takes a few minutes to delete large batches of your tweets. One major caveat: Because of a technical limitation, TweetDelete can delete only the last 3,200 tweets on your account. So to clear out roughly 14,000 tweets that were more than a year old, I had to run the app four times. (I’ve had a lot to say on Twitter over the last decade, O.K.?)
My Facebook timeline was tougher to manage. After skimming my last 14 years’ worth of Facebook posts, I concluded there was nothing worth keeping. So I opted to purge everything.
I installed Social Book Post Manager, a free add-on for the Chrome web browser. This app was more rudimentary: It essentially scrolled through my timeline and clicked on the “delete” button for each of my posts for me.
Social Book Post Manager lets you delete months’ or years’ worth of content — or everything, which I chose. The problem was, even after I used the app to scrub through my entire timeline six times, the tool missed about a dozen posts. There is a setting to adjust the speed at which the app deletes posts, and I had to choose the minimum speed to do a complete purge.
The process was agonizing: I watched years of my youth play back in slow motion, including dated, satirical jokes and photos of myself wearing vintage clothing back when that was a fashion trend, before the tool deleted each post one at a time.
Is It Worth the Effort?
After I finished scrubbing my Facebook timeline, I concluded that my delete-everything approach was probably not worth most people’s time. And even after all that time, my Facebook timeline was still decorated with posts that my friends had published about me — including photos from my 21st birthday (need I say more?) — because that content was not mine to delete.
Gennie Gebhart, a researcher who follows privacy and surveillance issues for the Electronic Frontier Foundation, a digital-rights nonprofit, found a simpler approach. She connected her Facebook and Twitter accounts with the app Timehop.
To help people reminisce, Timehop every day surfaces photos and posts published from years past on Twitter and Facebook. Ms. Gebhart uses the tool to incrementally audit her timeline to see if there was something from the past she might not want lingering around.
She said that she rarely found posts worth deleting, but that most people might enjoy this light exercise for peace of mind — and to protect their public reputations.
Facebook representatives said that based on feedback, the company recognized that people had different needs for managing their timelines. So it offers a privacy setting for people to limit the visibility of their older timeline posts. Similar to Timehop, Facebook also occasionally surfaces old memories from people’s timelines to help them reminisce.
Twitter did not respond to requests for comment.
Beyond the technological difficulties of doing a social media purge, you may decide it’s not right for you. Ms. Papacharissi, the communication professor, said people formed sentimental attachments to their memories on social media, as they do with clothing and old photographs.
“They present a timeline of who we were, of who we are now and who we would like to be,” she said. “It’s like this always-on story. It’s difficult to disconnect that.”
