It appears to be a bone of contention on many of the sites that subjectively lousy questions are being migrated/dumped on other sites rather than simply being closed as bad questions (the most recent example being http://serverfault.com/questions/276006/ ).
I would like to propose a way to downvote what the receiving site considers a "bad" migration with semantics similar to how downvoting an answer works. This would hopefully encourage the people voting to migrate bad questions to think twice before foisting their site's trash on a sister site.
Lest it seem that I'm singling out SO->SF migrations, I believe SuperUser gets the bulk of the community's trash - a lot of it from ServerFault - and hopefully something like will help keep their corner of the community cleaner as well.
Some numbers (motivated by @Shog9) -- Perhaps a data.stackexchange.com wizard can enhance this to split by close reason?
