I agree, the same things happen on IRC - my ip has been put into blacklist :(

One thing that Wikipedia's people could do is to actually disable anonymous editing
for the "blocked" IPs, allowing them to login.

Also, there is a way of blocking people by e-mail address, I am not sure if
MediaWiki developers had done that or not but i think that it would be a great
idea.
Especially when combined with Blocked IPs.
What i mean is that if the E-Mail is blocked and the user wants to register, theiy
should get a cookie and their IP address should be blocked until the ISP replies.
As well, a message could be sent to their E-Mail address saying that their E-Mail
address is being used for vandalising, and if they don't reply e.g. in 24 hours or
anything - they are reported to ISP.
There are lots of solutions but the thing is that it's hard to take control of
them.

Another idea popped into my head - just add a cookie to every user, with a unique
ID ( it can be the id of the Edit ), and add that edit's id into the vandalised
page list (Probably in MySQL, new table :/).
Whenever the user comes back online, they are monitored ( This does not apply to
people who are not Vandalising, only to logged people ).
They can be reported to the ISP with monitored addresses and dates/times :).
Only disadvantage is that they can simply delete the cookie file.
But still if there is more security, there is less troubles.
