The term SPAM was first used in the early 1990s to describe e-mail messages, not related to the topic of discussion and postings that swamped newsgroups.
Spam is flooding the Internet with many copies of the same message, in an attempt to force the message on people who would not otherwise choose to receive it. Most spam is commercial advertising, often for dubious products, get-rich-quick schemes, or quasi-legal services. Spam costs the sender very little to send -- most of the costs are paid for by the recipient or the carriers rather than by the sender.
One particularly nasty variant of email spam is sending spam to mailing lists (public or private email discussion forums.) Because many mailing lists limit activity to their subscribers, spammers will use automated tools to subscribe to as many mailing lists as possible, so that they can grab the lists of addresses, or use the mailing list as a direct target for their attacks.
Top Ten Blog tips! ways to fight SPAM!
1. Use a contact form. Don’t make your email address public. Especially not as a clickable link. Here are some more reasons to avoid using clickable email address links.
2. Use a different email for each site you sign up for. Then if one email account starts getting spammed, you only have to change it in one place. This is more to do with email spam than blog spam, though.
3. Use a different email when posting comments. Who knows if the blog you’re commenting on will keep that email private? They might start sending you messages you didn’t ask for with no way to unsubscribe. Best to use a dedicated email address just for posting comments.
4. Banning IP addresses. This is a bit extreme unless you notice some very clear patterns in the spam you receive. Also, be careful, as banning by IP can also block legitimate internet issue.
5. Moderation. This means that every comment on your blog will be held until you approve it. The downside is that it requires a lot of manual effort, and may not be an option for blogs that get hundreds of comments every day. However, if you can add users to an “approved” list so you only have to approve their first comment, this seems like a very sensible solution to the spam problem. Well, unless your blog attracts lots of new users every day and many of them only write a small number of comments.
6. Anti-spam plugins. WordPress users will probably know about Akismet, a plugin that analyses comments as they come in and attempts to flag the ones that look like spam. Generally, it works well, but no system is perfect.
7. Word verification. Also know as a CAPTCHA, this uses an image of distorted letters and numbers and requires you to type the characters into a box. Get it wrong and you have to try again. I think these are quite effective so long as they are easy to read
8. Closing comments after a specified period of time. This method works on the assumption that a few months down the line, nobody will want to add anything new to your post. Spammers seem to enjoy targeting posts that have long since disappeared from the front page of a site, hoping that the site owner won’t notice the spam.
9. Requiring registration. This is likely to limit your comments drastically, and is still not a guaranteed way to stop spam. It’s a good method for blogging networks or sites that offer more than just a blog, but it’s a bit too draconian for most blogs.
10. Turning off comments altogether. No comments, no spam, right?! OK, you might not get any comment spam this way, but don’t cut off your readers! This method is a bit extreme.
I have experienced as I opened up the mail box (hotmail) there are many junk mails and I didn't know about the sender as well. Actually all these is the SPAM email which is contains those commercial advertising, often for dubious products, get-rich-quick schemes, or quasi-legal services.
Besides that, there are also many messages that contain the "sex message" they will asked you to click and enter the web site sometimes all these is chargable. So becafeful when clicking it and identify the sender is you know them only click "show content".
