NAMESDATABASE.COM is a scam website that passes your email on to a wide network of specifically scammers.
It poses as a contact database for people over the world to reunite. In order to join up it asks you to submit 20 or 30 email addresses, then you and all these people will start to receive spam, which includes infections that get into your list of contacts and then sends all of your contacts spam as well, even if you did not give their email address to the namesdatabase.com website.
After joining I never stopped receiving emails about loans, lottery wins, beneficiary inheritance etc. I cancelled my subscription to the website but still received some of the related spam. I received complaints from friends about the same thing and saying that everyone in their contacts were emailed too.
