Prevent Spammers:

Many websites ask for email addresses at the time of registration. If you suspect the website may spam your inbox, then use any Gmail alias instead of real email address. And filter it or delete it automatically using the above method...!

Note : Some website does not accept plus (+) symbol. So at that time you may use the dot alias and googlemail alias.
