Once again, i see no way of preventing 1. If the feature is added to 
services, a script like the following will be created:

alias spam {
:loop
set %nick $rand(0,999999)
set %email $rand(0,9999999)
set %pass $rand(0,9999999)
/nick $rand(a,z) $+ $rand(a,z) $+ $rand(A,Z) $+ $rand(a,z) $+ %nick
/ns register %pass %email $+ @hotmail.com
goto loop
}

Its not likley that you can ban hotmail, as in excess 20% of any IRC 
Networks users usually have a hotmail accounts :P

although i agree with Suggestion 2.
