@JPB,
Thanks, but that doesn't change the point, which concerns the complete thread deletion - if the 3rd poster was really engaged in advertising, then a notice to the effect "we do not permit advertising linking to posters' sites" should have been left in lieu of the the post. Deleting an entire thread with perfectly legitimate questions and valid, well-researched replies is contrary to the entire stated purpose of this site.
For the record, I am most grateful to 2 moderators. First and foremost, my late friend Timberlandko, whose phone number I had and whom I could call on the rare occasions someone had posted my name by mistake on a thread - not a common occurrence, and since I know all the posters involved very well I'm entirely certain they were just being absent-minded. Second, the good person who was on duty on Ms Olga's anti-whaling thread (the starting point here), late at night in most US time zones, who did acted promptly on my request to remove erroneous duplicates of my posts:

Whoever that person is, he/she was already thanked by Ms Olga (on page linked) to which I'd like to add my own sincere thanks as well.
