In a move which marks a changed response by Twitter to Digital Millennium Copyright Act (DMCA) copyright notices, the popular microblogging site said that it will now "withdraw" copyright-infringing tweets, rather than remove them and show them as "disappeared forever."

It was tech site GigaOM which first reported the change that was announced on Twitter by one of the company's legal team members, who said in a tweet that the change which Twitter had brought in its "Copyright and DMCA Policy" was chiefly aimed at bringing about more "#transparency."

The change implies that a copyright-infringing tweet will henceforth be replaced by a notice which says that the tweet has been `withheld.' With Twitter having received nearly 4,410 DMCA tweet-takedown notices in 2011, the change does away with the company's earlier policy of making a copyright-infringing tweet `disappear forever.'

Despite the fact that Twitter message about withholding the tweet will still technically mean that the infringing content has been removed by the service, the changed policy will give the users more background details about the copyright-infringing material.

Elaborating on the change on its revised copyright-policy page, Twitter said: "In an effort to be as transparent as possible regarding the removal or restriction of access to user-posted content, we clearly mark withheld tweets and media to indicate to viewers when content has been withheld."
