You cannot avoid spam, try blocking one avenue for them and they will find another means for pestering you. Over the years we have got used to e-mail spam sitting coolly in our inbox but now get ready for spam even in your VoIP calls. Called as Spam over Internet Telephony or SPIT they will access you via phone call using VoIP and since these voice spams are ten times larger when compared to normal e-mail spams it could disturb the voice quality of the entire VoIP system since they take a lot of bandwidth. You will be amazed to know that there are more spam e-mails in the web world when compared to human generated e-mails. It's also quite easy to generate SPIT since the botnets need to be tweaked slightly for generating VoIP spams which are thousand times cheaper when compared to regular phone calls so probably you might be pestered by those sick adult ads.

With SPIT starting to turn its head time has come when something concrete must be done to prevent it from reaching a stage where it becomes a headache just like the e-mail spam.
