A significant proportion of questions being transferred to PSE from SO are being closed pretty rapidly upon arrival.
An example of a question which was transferred today which (to my mind) should obviously have just been closed is http://programmers.stackexchange.com/questions/88846/what-are-you-doing-with-cables-under-workrtable but this isn't an isolated case.
As a first step would it be possible for someone to write a script to see the percentage of questions that get closed after being migrated - possibly breaking it down between those migrated unanimously and those where there were also votes to close for other reasons?
If that shows that a significant proportion do just get closed, instead of them just appearing, would it be possible to have them transfer to a holding area where they can be reviewed (by mods or suitably rep-ed up users - appearing in the tools area) prior to appearing on the site? I'd suggest a threshold of two (or more) users have to accept the question.
If it's accepted then it appears as normal, if not then it gets returned to SO closed with a comment explaining what's happened.
Sometimes it just feels like SO is the neighbour who keeps their garden tidy by throwing all their rubbish into yours...

EDIT: In terms of it's an isolated example:
I've stopped at five (plus the original one), all from the past five days, all closed and I've excluded those closed because they're duplicates and one or two that were closed that I personally think are fine.
I get that people don't necessarily know the ins and outs of Programmers but if that's the case then surely they shouldn't be migrating stuff there.
