Just when I think I'm too much of a misanthrope . . .
. . . multiple people who went on my DoA Ignore list months or years ago (because their very first posts made me want to snap knitting needles in two) turn up in Problem Transactions, revealing themselves to be the most egregious kind of cut-and-runners and winding up with Marketplace bans.
From now on, just think of me as the Delphic Oracle of Ignore.
