I got 15 points for an "accept" today. It was a while since I'd answered the question, so I clicked on the link in my profile to remind myself.
Here's the link from my profile that I clicked on: https://stackoverflow.com/questions/6816301/seo-which-urls-are-the-best/6816457#6816457
It turns out that the question has been migrated from SO to Webmasters.
That's fair enough; it's probably better there, but I posted my answer on SO before it was moved.
What surprises me is that the question now has a different accepted answer, and in fact no longer has my answer at all.
Presumably (given that it was accepted) my answer was reasonable, so I'm surprised that it's been deleted. What's happened to it? Additionally, given that a different answer is now accepted, why have I still got the points for the acceptance?
