Unfortunately this is not the case. There is a loophole in Majordomo
which lets you subscribe and unsubscribe other addresses without their
consent, bypassing the approval process (for open lists). I have
complained about this is in the past, but the feeling seems to be that
this is a feature, not a bug, and it won't be fixed. However, it would
definitely be possible to crash a list in this way.
In my opinion this is the most serious problem with Majordomo, and one
of the items on my agenda is to learn enough perl to be able to hack it
so that at least the version that I use here will not be vulnerable.
