Encourages spam.
For some reason, one day I looked for various e-mail providers apart from top e-mail services such as Gmail, Yahoomail, Hotmail etc. During my search I stumbled upon this site and since it look reasonably good I decided to make a email account with it. After a few days when I rechecked my account, I found it bombarded with spam. Since I had not given that email address to anyone, anyone at all and yet there were a lot of spam emails I concluded that the site administrators themselves were encouraging spam emails. Therefore this is not a good site in my opinion.
