Is this spam?

On my blog, I received this comment. I replied to that.

However, today, I received this comment and this comment, and when I saw those listed above each other my first reaction was “oh, more spam again”. Then I saw that the former was a reply to my reply to the first comment. However, the latter came out of nowhere.

So now I’m wondering whether the first comment is just intelligent automated spam? I mean, I can imagine that a bot would be smart enough to refer to screenshots and a word (“panel”, in this case) that occurs frequently on a page.
