Create a simple disposable email address or trashmail to protect you against spam. For example some insurance website would like to collect your real email address to send you newsletter or spam which contains advertising.
Adveritsing from such companies could be interessting, for example some loan offers etc. The problem is that mostly its not easy to unsubscribe from such mails, or its complicate and take time. In some case you need to take a lawyer to get rid of this spam.
You don't need a degree in computer science to understand that the best you can do is to simply not publish your real email address. This website is for people who have their own email hosting service but simply want to hide their real email address.
So enjoy the website, and if you like, you can send us a donation, but we don't claim it.
