Update: The threads in question have been deleted and the poll is now moot.

Alas, I cannot edit or delete the poll. Thanks for your interest, and thank you Eric!

John Doe, a/k/a "Lazard," a/k/a "Ramon Campos," a/k/a "C.Menuat" has been posting pretty stolen images and interesting plagiarized articles in this and other forums for years. Some were even purloined from our fellow Geeks whose protests have been ignored by Mr. Doe.

Should the threads be wholly:

1. Kept to exploit the goodies despite their dishonest origin, or
2. Deleted to respect fellow Geeks' rights despite losing the pretty pictures?
