Twitter messages are quickly written and published. Just as quickly they're forgotten - yet they're still available and can be found by search engines. Over time the 140-character text messages accumulate. For those who want to keep their digital archive small, there are services like Tweet Delete.
Once you register your Twitter credentials with Tweet Delete, you give the service the authorisation to delete your tweets. Up to 3,200 messages can be removed at one time and it's also possible to delete all the tweets over a specific timeframe, for example for a period of one, two or three months.
The service is free. Questions about data privacy and data protection are explained in a FAQ on the Tweet Delete website.
