How can I test if an email address is a spammer's?
I received a reply to my Craigslist post, with a gmail address in the email body. Craigslist uses some way to hide my email addresses, if I choose to reply directly. But I replied to the gmail address provided, and immediately got an email which I recognized as spam. At the same time, I regret having revealed my true email address.
Now I received another reply to my Craigslist post, with a different gmail address provided in it. I replied via Craigslist, and have not received anything yet. I wonder how I can test if the gmail address provided is spammer's?
