I'm guessing that this agent approached these so-called clients -- all writers deperate enough to use a vanity publisher -- and not vice versa. I'm not saying these writers are hacks - they may all be brilliant - but like so many good writers haven't been able to get their foot in the door of a good literary agent. We all know it's a tough go, but persistence and good writing will eventually pay off. I just hope they haven't hitched their star to a wagon with a broken axle. I suspect, though, that they have.
That being said, to list these as clients on your Pub Marketplace webpage, implying (I believe) that the agent has "Sold" these self-published books, is deceiving. And if a writer doesn't do a little checking on said client's publishing credits, that writer could end up signing with Krista based on her previous "sales."
I agree with Miss Snark on the issue of bad agents: I'd rather have no agent than a bad one, i.e., someone who locked up my work, gave me false hope, only to tell me a year or two down the road that she couldn't sell my work because the market wasn't there; the writing wasn't good enough; whatever - anything but the truth which would be that she has no connections and no idea what she's doing.
We all come to this forum to help each other avoid disaster. Yes, we're all hungry and in many cases desperate, but if we're here, we're not stupid.
