He's been here all along.

He doesn't understand the nature of spam, and uses "spammer" as an
insult
(as he did with Bill McKee). That narrows the field considerably.

The exhortation to "seek help" is another clue.

Watch his style and phrasing. He gives himself away very easily. If and
when he ever outs himself so obviously that he has to admit his
behavior, I predict that you will not be surprised at all.

Our net cop, if it the party whom I suspect, is also a gargantuan
hypocrite in this regard. Once again, you would not be surprised.
