These 2 questions have clearly wrong answers with upvotes. And they're still getting votes.
The log file one especially could be tried out, it would fail, but someone still voted it up. A downvote and comment has no effect.
Like we have "vote to close", what about a "vote to delete" for answers. I'd suggest a fairly high rep limit. Or badge ownership realting to the question tags (eg SQL Server)
What is an MDF file (SO)
Could be similar to this meta question: Question with wrong answer upvoted
