I Didn't Get Your First Message

As with all online dating sites, you run into the same people. Obviously, it's extremely difficult to keep track of all the hotties you message. Well at least for chocoxx. His message read as follows:
chocoxx: Hello how is it going?? Would you like to have a cup of coffee and talk sometimes?? :) btw I am David
I wasn't really interested. I didn't find him attractive and we didn't have any similar interests, as far as I could tell. So I didn't feel the need to message him back.
The next day, I received the SAME EXACT message from chocoxx. Honest mistake, right? I'm sure he was messaging so many women that he didn't realize that he messaged me already. Again, I felt no need to respond.
The very next day, I received the same exact message for a THIRD time, from the very same guy, chocoxx. Okay, now I know that wasn't a mistake. Get a hint buddy, not interested. Once again, I did not respond.
So two days go by, and I receive ANOTHER message from him; reading as follows:
chocoxx: What do you think about my little doggy??
Excuse me! Does anyone know what this means?
Irregardless...I blocked him.
