As funny as it may sounds, spam and party have a lot in common. Let me explain you. When you are organizing a party what you do? Except of buying alcohol, food and so on, the most important thing is a list. List of invited friends. Than at the day of party you do not leave your door wide open with a sign “you are all very welcome” Why is that? Because that would lead to a serious disaster and unknown people running at your house. What you do than? You check invitations, usually not you but a bodyguard at the entrance. Now think about you mailbox as a party. Do you want every one to get in, without any invitation? Do you want unknown messages in you mailbox? Surely not! So what do you need to do? Hire a bodyguard. Luckily is that hiring electronic bodyguard called antispam tool is cheap or even free. Choice belongs to you, if you want to pay few dollars or just use the free of charge version. However that is how it works, your electronic bodyguard ( spam filter ) will now  stay in your mailbox entrance door and check every email that would like to get in to your mailbox. So? Have I proved that spam and party have a lot in common? I doesn’t mean that never ever uninvited guest won’t get in to your party but that would be an exception.
