So I listed a couple of things on Craigslist and I have been getting replies from @reply.craigslist.org email addresses. Are they fake? I was looking and I could not find a way to reply to an ad and generate a @reply.craigslist.org email address? Is this through an app or something or are these just a form of spam? The craiglist help section is no help on this subject.

Thanks in advance!

So when I reply to the reply are they masking my email address too?
