Launchpad should lock "special" names... today someone added himself to the ubuntu-ve launchpad team... what got my attention was that lp allowed him to use "contactame" as lp id... which makes a very interesting issue... a user could get a ubuntu-membership and then later change his/her lp id to contactame... so his email address would be <email address hidden> (which means: <email address hidden>) and would lead to a BIG risk...
just imagine: a user comes, creates a lp account... makes himself with a ubuntu-membership, then changes his lp id to something like "<email address hidden>" or "<email address hidden>"
i suggest that "critical" words should be rejected (words in many languages... or words in the principal languages of the world...)
Can you update our blacklist to include contact*, Stuart?
