Of llambda's 10 most recent submissions, three have the exact same pattern. Two more have do-nothing query strings. Perhaps there's some other explanation, but much the most likely seems to be: When llambda finds something already submitted, s/he modifies the URL and submits again. Please don't do that, llambda: the dupe filter is there for a reason.
