A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is the distorted text that a person must solve before a new account can be created. It used to be hard for computers to translate the text, but improvements in OCR (optical character recognition) technology have overcome that barrier. In some cases, spammers are believed to employ people in low-income countries to figure out the CAPTCHA in order to gain new e-mail accounts.
Once a new registration is complete, the account details are then e-mailed to a spammer. After too many account registrations, Google will eventually block the particular computer creating the accounts. The worm then removes itself, Dung wrote.
Facebook has won an $873 million judgment against a Canadian man who bombarded the popular online social networking site with sexually explicit "spam" messages.
2 days ago I got a bit surprised when I check my guestbook, I saw spam inside there and filled up the first 5 entries. Because of I using Joomla for this content, usually I can delete it through my back-end but I got nothing. I don't have any experience about this issue, but I must to fixed it up as soon as possible, it was annoying me and most of the people which are read my blog. I have a certain thought that all the system stores in the database, and I check my database and try to find out the component for that particular guestbook. It takes 2 minutes and I got my guestbook normal again and running smoothly.
