You might want to skip the intro and read what happen first.
The block system doesn't work if a vandal logs out before being 
blocked and then logs in with another username - see below.

Today on the portuguese Wikipedia, a vandal registered a 
account (Didimocó) and started moving some admin user pages - 
and later some pages in wich some admins where editing - to 
titles with insults, see
Contributions/Didimocó for examples. But then after he was 
blocked he would register another account and start moving more 
pages and the block didn't have any afect on him.

Me and another admin (Nuno Tavares) made a test [1] and we got 
to the conclusion that the vandal before being blocked simply 
just logged out and then simply logged-in with another account. 
The vandal finally ran out of luck and I got the chance to 
block him before he could log out of the account, blocking this 
way the ip he was using.

Well, I'm not sure if this is a bug, and if so, please change 
the Severity field to enhancement.

Best regards,
[1] Nuno Tavares logged out of his account, and then I blocked 
him, after the block he edited a page using another account

What do you mean by "the block system doesn't work"?

You can block:
1) IP addresses
2) IP address ranges
3) User accounts

If a blocked user account gets used for editing while the block is in place, an
automatic temporary block on the IP address is also added by the system.
Comment 2 Nuno Tavares 2005-10-02 23:19:25 UTC
Can it be based on ''last IP used'' for that account for a specific time? It
could set and auto-expire... that would prevent this issue. 
Comment 3 Brion Vibber 2005-10-02 23:58:27 UTC
Probably could; originally we didn't record the IP in the database at all, but
for recent edits this can be extracted from rc_ip.

I'm duping this up to bug 5149, which describes a similar thing, but has more
