Whenever there is a new online service or web software introduced on the Internet, in a month or two, you will expect someone or some”thing” to start spamming it.
I have just registered for a Twitter account and to prevent these spammers (usually robot) from being my followers, I signed up with TrueTwit which could assist in validating my followers
