A friend had sent me this URL link to an article that tells how spammers are trying to stay ahead of the game of anti-spamming software.
They tried breaking up words with '.' or special types of characters, anti-spamming software is cracking down. They tried using invisible yet meaningless HTML tag codes... anti-spamming software is cracking down. What's left? Literary works ... complete passages can be found embedded in the spam message in the attempt to fool the anti-spam software that the spam is a legitimate piece of email.
Sometimes I wonder, do spammers get spam mail too? And do they suffer the same inconvenience as the rest of us? Or do they all share some kind of 'escape' code that prevents spammers from sending spam to other spammers?
