Out of curiosity, do you have an automated system that checks for duplicate comments? Did you just happen to read it before and remember it?
The third and most likely option is looking up the poster's HN profile and checking out historical comments made by the poster.
I guess the idea of looking a person's profile is foreign to me. Perhaps I should get into the flow of doing that.

I also read through the comment thinking.. deja vu?
But yeah it was a copy paste from three weeks ago.

No automation. I had a feeling I'd read it before, so I checked the profile.
You're far from the only one using HN to advertise your business, but maybe you should try to mix it up a little.
18 days ago was in November. Did a client call you a 3 am in October and also in November?
