You mentioned that you couldn't use "defdac" because it was taken, and then you mention you had a flickr Pro account using "defdac"?
Was it taken because YOU took it? It doesn't make sense.
Later you refer to the fact that the message said it shared the same email address. Couldn't you sign into the PRO account , change the email address, and log into your defdac2 account?
The flickr username is not the same as your yahoo username. They are linked, but can be different strings. You sign in to flickr using your yahoo username (ie, your @yahoo.com email address) but your flickr username is a completely different string.
The reason for this, I suppose, is that flickr was an independent entity, with its own user database, before being acquired by yahoo. It was long after the acquisition that yahoo insisted on linking it to your yahoo ID. Some will remember the brouhaha that caused.
