> 1. Massive downvoting of nodes belonging some specific user.

This is quite difficult to spot and you got already replies with many shades. There are things ragarding this that can be added: dogvotes are already taken in count by the system, so theorically you can match dogvotes by user against user per day.

Anyway if a user posts many bad quality nodes in the same day leave us the possibility to downvote them all.

Another thing worth to consider is the ratio XP gained from upvotes received / XP gained voting and relating this with the dogvotes used.

These are quite plain: they are already prohibited and rare dual accounts are granted by gods for particular purposes. I think these accounts are already blocked in the voting system, no?

As side note consider the following:

perl -MLWP::UserAgent -e "print LWP::UserAgent->new->get('http://perlm
+onks.org/index.pl')->header('x-meta-keywords')"

perl, mod_perl, regular expressions,
                     regexp, xp whoring, CGI, programming,
                     learning, tutorials, questions, answers,
                     examples, vroom, tim, node, experience,
                     votes, code
[download]

Is true that x-meta-keywords are no longer used by search engine (having them wrong is still wrong btw) but xp whoring surprised me :)

Can you consider updating them? With modern web frameworks, Tk, Raku etc..
