cantueso on "user name vs address name"

I used to have just 2 WordPress blogs. They had each its wordpress address, but I was "cantueso" in both.

Now I opened a third blog and rather carelessly called it "3violets" at WordPress, because I thought that this address name didn't matter.

However, now, when I comment on other people's blogs, there I sometimes see myself named "3violets", and I don't like it much at all.
