"In Perl culture ... you're expected to stay out of someone's home because you weren't invited in, not because there are bars on the windows."
--Larry Wall, Tom Christiansen, and/or Randal Schwartz in "Programming Perl" second ed. p. 278.
The thread you linked to in your post seemed to have a quick back and forth which ended with the 'perpetrator' acknowledging that he was unaware that it was considered in poor taste to front-page one's own node. It looks to have been a worthwhile exercise. The original poster learned something about the culture here, and so much the better.
I like it that there are very few windows around here with bars on them...
