Dear Mr. Lepant,
Your eloquence and reasoning are wasted on the robo-spammer deuxieme, a.k.a. Ray Ancle, e3troit, Olive Hoyle. . .for the sake of brevity I'll omit several yards of aliases. He repetitively posts his drivel, some of it several years old, sometimes under several names simultaneously, on every thread, but almost never engages. TH bans him, and he returns within a few minutes to pull the same stunts again. He's so relentless and prolific that I have to believe he's a paid disruptor.
Perhaps you can take some consolation from knowing that real people appreciate your posts.
