OAuth is an authentication protocol that allows users to approve application to act on their behalf without sharing their password. If your Twitter oauth Secret Key and Token get compromised , then application or Hacker can user your Twitter account on Behalf of Your access. You can get sample script here. These accounts can be used to spam over 10000 of compromised twitter accounts.

Also if hackers are able to compromise the keys of popular applications like TweetGif and use those keys to evade Twitter's abuse controls. By using the consumer key and consumer secret key from a popular third-party Twitter application, a spammer can make it harder for Twitter to lock out all of his spam accounts at once without also locking out a large number of legitimate users of the compromised application.
