Question for the flist...

I recently received a invite to Tagged from someone on the flist. After looking into Tagged, it seems like more of a way to harvest people's info than a worthwhile social networking site, so I dropped the person an email to let them know that I was not going to be joining Tagged, and why. They responded that they hadn't sent me an invite, but had received one from me at about the same time, and had decided to ignore it for more or less the same reason. The primary online connection between us has been LJ, and I'm curious to see if anybody else on my flist has received Tagged invites from me. Because if Tagged is mining LJ, that would be a major scumbag thing to do.

Thanks for your help.
