<email address hidden> is spamming launchpad translators

I'm not sure if there's much you can do about it, but I asked on
#launchpad and lifeless suggested filing a bug, so here's the mail
I received:

Hi Olly Betts,

I saw you involved in French translations for Survex Cave Mapping Software at Launchpad so I would like to ask if you could help me out in translating Vector.us.

Vector.us is a search engine for free vector graphics with probably the most extensive database of free vector arts. I created a simple web-based translation system similar to Launchpad's at http://vector.us/translate. Currently around 160 translators are already on board.

If you would like to contribute, please reply to this message and I will create a translator account for you. Or just ignore it and you wont receive any messages from us.

Every translator will get a link from Vector.us at http://vector.us/translate/contributors. We will appreciate your efforts to make this site more native to all people around the world!

Greetings

Henry

Analysis
========

Vector probably got the email address from PO files exported to Ubuntu. We include contributor email addresses in those files unless the address is totally hidden (see bug 362848). If we were to use a pointer into LP as that bug discusses, this would be less trivial - and this would also avoid a vector leading to these email addressses getting into search engines.

It is possible to solve only one of these symptoms, so keeping as two bugs for now.
