If you see a warning about an unsafe link on Twitter, this means the URL matches a database of potentially harmful URLs which may lead to malware, phishing or spam pages.You may see this warning when: Unsafe sites include phishing sites that attempt to steal your login information and password, sites that download malicious software onto your computer, or spam sites that request personal information.
If you manage the website of a URL flagged as unsafe, contact Twitter Support. These are people who will look you in the eye and lie. If you look up a business and call to make an order, you know who is on the other end of the deal. It is almost always a large sum of money, like a prize or an easy loan, or a large income. But we all know that people don't give away large sums of money so easily, or pay large incomes for nothing. It is illegal for someone to require up-front payment before funding a loan or paying out a sweepstakes prize. Decent, intelligent people are duped out of their life savings by smooth-talking, utterly unscrupulous crooks. Anytime someone tries to get your bank account number, Social Security Number, or other sensitive information, you should automatically be on red alert. If they are asking you to give them money first, back off.You have been warned about mail fraud, telephone fraud, internet fraud and door-to-door fraud. Whether they reach you by mail, by phone, by email or by talking to you in person, they will give themselves away if you know what to look for. With a con artist, all you know is who that person says he or she is. And real employers don't generally ask new hires to shell out money.If the URL of the site you manage is being blocked, and you are completely sure that your site is not being used for abuse on Twitter, you can contact our Support team by filing a ticket here.In the Problematic link field, please insert the extended URL of the link you are having issues with, rather than a shortened version.
