Swiftly deleting abusive tweets may save offenders from being brought before court, the country's leading prosecutor has said.
Keir Starmer, director of public prosecutions, said it was "relevant" for police to consider whether an offending tweet had been quickly deleted from the micro-blogging site.
Speaking to Sky's Dermot Murnaghan, he said he was holding a three-month consultation about the plan.
Libellous tweets, or messages which broke court orders or were threatening, would still face prosecution regardless, he added.
Starmer said: "There's a lot of stuff out there that is highly offensive that is put out on a spontaneous basis that is quite often taken down pretty quickly and the view is that those sort of remarks don't necessarily need to be prosecuted."
He added: "I think that if there are too many investigations and too many cases coming to court then that can have a chilling effect for free speech.
"This is about trying to get the balance right, making sure time and resources are spent on cases that really do need to go to court, and not spent on cases which people might think really would be better dealt with by a swift apology and removal of the offending tweet.
"This is not a get-out-of-jail card but it is highly relevant. Stuff does go up on a Friday and Saturday night and come down the next morning.
"Now if that is the case a lot people will say that shouldn't have happened, the person has accepted it, but really you don't need a criminal prosecution. It is a relevant factor."
But he said Twitter was not a place where people could "go and say what they like" without thinking of the circumstances.
Pictures Of Your Debit Cards
Stop with these photos! Seeing your account number and name is too much information to willingly give away. To curb this recent trend, <a href="https://twitter.com/NeedADebitCard" target="_hplink">@NeedADebitCard </a>has started calling people out on Twitter who pose with their plastic.
Too Many Hashtags
#One or #two #hashtags is #enough, #people. Also is #FF an outdated fad yet? #Itshouldbe #Imsoironic. Oh and #PS Don't you love #ridiculouslylonghashtags?
Requests For Retweets
There is a certain desperateness if all of your tweets scream "Plz RT!" or "RT if you love this!" We probably won't do as we're told.
Your Own Twitter Handle
That's like talking about yourself in third person. (And you probably shouldn't do that either.)
Ah, the humblebrag: "People keep telling me I look great today, but I'm so fat!" "This picture of me is horrible, but thanks for all the compliments!" The only boasts we like are those aggregated by <a href="https://twitter.com/Humblebrag/" target="_hplink">@humblebrag</a> -- and that's because all of your subtle swagger is being mocked.
We know you go out with your friends on Friday night. And that's totally fine -- but maybe when you puke in the back of a taxi at 4am, you should keep those tweets to yourself? Or maybe not... We kind of like reminding you to delete them the next day.
Your Klout Score
So you're influential about the topic of "coffee?" Wow. Your klout might <em>actually</em> be worth a #humblebrag.
Rapid-Fire Instagram Pics All Day
We love Instagram. But, alas, there can be too much of a good thing. It's bothersome when you tweet 17 pictures of your dog or your baby a day. And might that also <a href="http://www.huffingtonpost.com/2012/06/26/instagram-tips_n_1557614.html" target="_hplink">annoy your Instagram followers?</a> For a fun little Insta-mocking Twitter account, check out <a href="https://twitter.com/textigram" target="_hplink">@textigram</a>, which tweets what your photos would be if they were described via text. "Latte with heart shape in foam" and "Wing of airplane, hashtagged #flying" are some recognizable examples.
'Good Morning' Tweets
Imagine if we all tweeted "good morning" or "good night" with no updates, anecdotes, or witticisms. The Twittersphere would be a pretty boring place. Don't put us back to sleep in the a.m.; resist the early morning greeting to no one in particular.
Food Pics At Every Meal
Especially if they are photos of the fast food variety. We can only see but so many Dorito tacos and Jr. Bacon Cheeseburgers.
Every Place You Check Into On Foursquare
We don't want to see an automated message about your trip to Dunkin' Donuts every morning.
Tweets About You Working Hard
It makes us feel lazy, especially on a Tuesday night when we're out at dinner.
Passive Agressive Tweets
These tweets are awkward, angsty, and remind us of MySpace circa 2004. Just take a punch, why don't ya?
There's a reason why some of us don't follow Kim Kardashian or Katy Perry on Twitter. Kindly keep the latest gossip on your own newsfeed.
Tweets About How Many Followers You Have
You win some; you lose some. Either way, we don't really care about your follower count just like you probably don't care about ours.
