Imagine that I want to try an online service but they
ask me to use my e-mail address and create an account. I don’t know whether I
will like it or not so, why do I need to create an account? Anyhow, I decide to
continue, I can’t resist using it, so I type my email address. After 5 minutes,
I receive about 3 emails, and at least one every day in the following days. I
shouldn’t have made that mistake, I think.
This is only an example but, probably, everyone receives a lot of spam only by using
an online service once, so I decided to help you prevent all that junk!
