Being blacklisted is one of the worst things that can happen to a website. The public shame coming from every visitor being stopped by the Big Red Warning page can literally destroy any online business, I am speaking from personal experience before joining the Sucuri team. When a website is blacklisted, users are unable to access the website without specifically agreeing to take on the risks. As a result, blacklisted websites lose around 95% of their traffic.
The following is a true story, based on my personal experience with a blacklisted website. This is actually how I came to know of Sucuri, and how I now work for them as their Social Media Specialist. Have no fear, nothing has been changed; these are real names and events. No additional websites have been harmed during the writing process.
