Assuming good faith here, I think there might have been a misunderstanding:
The person you're replying to, didn't call any person "blogspam". That would be rude, and I wouldn't call ipsum2 rude.
They didn't even call any blog, "blogspam". That would also likely be rude, and again, I wouldn't call ipsum2 rude.
They called this particular post, "blogspam", because that is a good definition for a blog entry which reposts someone else's content without adding much beyond the original content, which is an accurate description of this blog entry.
Note that this definition doesn't describe a person, it describes a behavior. Misinterpreting feedback about a behavior, to be feedback about a person, is likely to lead to such misunderstandings. If we can make sure to tell the two apart, we can eliminate some of the strife in the world at no cost :)
