It looks like Guy Chapman is definitely reading this list and is active on Wikipedia -- http://en.wikipedia.org/w/index.php?title=User_talk:%24_London_Apartments&am.... He still hasn't answered my polite e-mails, though, so I have to conclude he's just being arrogant and rude.
It also appears that the Stalinist hive-mind has a "flexible" definition of what constitutes "spam". A few "nofollow" links to London apartment pages on a User page = spam. Nearly 3,000 links to a for-profit Google AdSense funded operation that gets exemptions from "nofollow" and often points to wikis that have, at best, two active editors in the past month and/or less than 5 edits overall in a month = not spam. Reporting on this "not spam" = blockable offense from an admin who ignores e-mails.
If you Wikipedians are proud of this type of work, keep it up. It only generates MORE of an urge to expose the hypocrisy.
