E-fedding has always benefited from a few undercard joke characters every now and then. Heck in PWE when I ran that place I pushed CM Punk with a fish for a head as my Next Gen Champion (newbie division) for months because he was literally better than that rest at that time. lol.
Plus, Duffman will have to get back at least a week of Dark Matches to test himself to make sure he's gonna show up. After that, with Sam Caldwell already in an upper midcard title/personal feud that we discussed earlier last week, I doubt Duffman is getting anywhere near Caldwell. So you've got nothing to worry about.
Besides, just don't read his rps if your afraid he's just joining to mess with you. It'll only hamper your experience here and I PERSONALLY don't want that. As even if I am just the Dark Match writer and don't hold much sway, I take particular responsibility in the happiness of IWF's roster. Hence why if anybody ever has an issue, my ear is always open to questions, comments, kudos & complaints.
