If you see a warning about malware or spam when you try to take the actions listed below, this means that the link/URL matches a database of potentially harmful URLs:
- When you tweet a particular link
- When you add a particular link to your profile
- When you visit a particular link through Twitter's link service, http://t.co
What's a potentially harmful site?
Harmful sites include web forgeries ("phishing" sites), sites that download malicious software onto your computer, or spam sites that request personal information. This could also mean the website was compromised by a hacker at some point, and the hacker embedded malware onto the website.
How to clean a website or get it un-flagged:
If you manage the website of the reported URL, please take the following actions:
- Check to see if the URL is a suspected malware or phishing site. If you manage the website of the blocked URL, you can view Google's diagnostic report on the URL by visiting this link: http://www.google.com/safebrowsing/diagnostic?site=http://example.com (You'll need to replace "http://example.com" with the URL that is blocked.)
- If your website is showing up as a malware threat because it's been hacked or compromised, you can find out more information on how to clean your site of malware threats at Google's Resources for Websites and Site Owners. You'll need to clean up any outstanding malware threats before your URL will be unflagged.
- Even if Google's diagnostic report of the URL is clean, we may decide to continue blocking the URL on Twitter as potentially harmful.
- Contact Twitter Support. 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.
Why does Twitter flag URLs?
Twitter Flags URLs for Account Security and User Safety. Twitter blocks the posting of suspected malware URLs, and flags suspected harmful shortened URLs, in order to make Twitter more secure and to prevent phishing and scams. Our Safe Tweeting help page has more general information on keeping your account secure.
