There are a few ways to fight spam. Well, fight may be a wrong word. There are ways to stop spam from polluting your inbox. Spam filters are the best programs to do it because when you use them you do not risk that your spam blocker blocked an important message that you were waiting for from reaching you. The simplest spam filters search for keywords like “xxx”, “sex”, “sale” etc. in the subject line of the messages that are being send to you.
If they find any of those then those programs put them in special folders. You can always view those spam messages and see if there is something that you actually want to read. If not then you can delete those messages or simply wait for 30 days – after that time those messages are being deleted automatically. It is wise to check every day your spam folder because there could be placed among the junk a message from your friend, boss or a colleague. But what is most important in fighting spam is to be careful with giving away your address.
Of course you cannot prevent your inbox from getting spammed but at least you can decrease the amount of junk you get. I hope that someday someone will make a program that would deal with spam for good. Lots of people would pay for such a thing lots of money. Anything to get rid of spam.
