Twitter is a social networking and information-exchanging program that allows you to send short messages out into cyberspace that have 140 characters or less. These messages are called "tweets." Twitter can be a valuable source of knowledge and information as you're getting facts and intelligence up to the minute. If you tweet daily or several times a day, you could quickly store up hundreds of old tweets on your profile. There's truly no reason to hold on to those old tweets and luckily there's a way for you to delete them without manually doing it one by one.
Visit a website like "Twitlan" or "Twitwipe" or a comparable site. Click onto the "Sign in with Twitter" icon on the centre of the website.
Type in your Twitter username and password. A new window will open, saying that a program such as "Twit Wipe" or "Delete Multiple Tweets" would like access to your computer. Click on the "Allow" button.
The program will then load your last 100 tweets. A button will pop up which says something to the effect of "Delete Tweets Permanently". Click on this button. You can now type in more tweets to load for mass deletion such as 250, or 350 or allow the program to delete them in increments of 100. You can also stop at any time.
