Has SO become the trash dump of Programmers?
The specific question certainly isn't... stellar, but you are over-reacting. In fact, of the 258 questions we've migrated to SO (in the last 90 days), only 13% have been rejected. Conversely, the numbers aren't as good the other way around. We've rejected 16% of the questions SO has send us (but you don't see us complaining about it, do you?but you don't see us complaining about it, do you? ;).
Next time you spot a shady migration, just vote to close it and move on.
