In reply to Robert Trevellyan.

Thinking about this some more, my guess is it's mostly a language barrier issue. The registrant's address is in Russia and it seems reasonable to assume English is not his first language.

If you rewrite "We have already talked to WordPress support team ... who asked us to contact you with such a request" as "We have talked to the WordPress support team ... who told us we should contact the plugin author directly with such a request" then it doesn't read as an attempt to claim legitimacy by association.
