This article is all about spam(as you may have correctly guessed). Ironically, the following thoughts were triggered of by a friend calling one of my previous articles appearing on Buzz as spam(he called me a spammer; and if he repeats that, he has absolutely no idea of what I have in store for him).
So, spam. Defined as “unwanted, junk mail”. And at this point itself, I realize that dozens of spamblockers fail simply because they pay no regard to the “unwanted” keyword in this very basic definition. Unwanted according to whom? For most spamblockers, the criterion is “unwanted according to most of the world”. That is because most of them work by ranking sources of mail on a scale of 10, say, and all those who score below 3, say, are considered sources of spam. Each time someone marks a mail as spam or not spam, the ranking of that site is inched slightly up or down. Which means that if a good part of the world thinks that a source is a spammer, and you happen to value that source more than others (for instance, you might be genuinely interested in all the drugstores and their “pleasing” products), spamBlocker doesnt care, and your marking all those mails as “not spam” will have to counter millions of others who marked it as spam; implying that for you, all such mail will go into spam.
Bottomline: If the world thinks a site is bad, then spamBlocker makes that decision on your behalf as well.
Now the funny part: this works the other way round: if the world thinks a site is good, then spamblocker will put it into your inbox, no matter how irrelevant it may be to you. In particular, if by a lucky streak, I happen to co-host my site on a server with some other reputed small-time organization, we’ll naturally share our mailservers, implying that many spamBlockers think that my site has a high reputation; consequently, all my mail has natural anti-spam protection!
Food for thought.
