Well, that's not really accurate, but most
blocked users can no longer
us a
different Userid to avoid the block, precisely
because Wikipedia blocks
the
IP address when attempts are made to do this.
That wasn't the case
before
the IP blocker was added.
You're not listening at all. I was editing only with my User:Njyoder
account, not a sock puppet nor logged out. If you block a username, it
has _always_ been the case that that username can't edit.
Right. This feature stops sockpuppet editing (at least for fixed IP
addresses).
