:Please try to rein in your temper - I'm trying to help you by blocking a disruptive user, and it's not encouraging to see someone lose their temper at me because I didn't do it the way they think I should do it. We don't block IPs permanently except in the most exceptional of circumstances. IPs aren't permanently tied to the people who use them, and there's no reason as of yet to think that in 48 hours, that IP will still belong to the person who was vandalising today. I'm not a checkuser, nor am I am expert in sockmasters, but in this case that's unlikely to matter, since all we have is an IP, not an account (which could be blocked permanently). Someone who is more familiar with socks is already looking at the situation, at my request, but I doubt they will be able to do much more than I've done.
