Please forget what he did for a moment and concentrate how he did it.

Multiple log-ins.

This can be checked against IP and email addy at registration automagicly... and should be... but apparently it is not.

If not, anything that is decided by one member, one vote on maemo.org could be affected.

How many votes decided the membership of the Community Council?
How hard would it be for bogus member #1 to thank bogus member #2 in order to build karma.. and so on?
Now that this is out in the open, I can say that this is what prompted my objection to reporting vote tallies while the polls were open in the last election. When given a goal to achieve, some people will find inspiration.

This is what has always motivated me to question why the hell single sign-on across maemo.org sites has not been initiated. It would make cross checking a whole lot easier.

What this fellow did, and how he did it, did not require an advanced degree in rocket science. Preventing, or at least reducing the possibility of multiple log-ins doesn't either.

Who can make it happen?

What can, and is being done about that?
