I came across this suggested edit and this one later on the same evening. Normally, I would reject it as it is answering the question posed and completely changing the post. But the problem is that it is suggested by an anonymous user, so if I reject it, it will be lost for good — and although I am completely unfamiliar with sockets, the answer-to-an-answer-posed-as-a-question seems well-informed and I would probably upvote it if I was certain of the validity.
In the meantime, I have clicked Not Sure but I am concerned that we might lose valuable information from anonymous users who are not willing to create an account and post a full answer. This has now been rejected, and it seems a shame as it was approved by another user (who probably understood it better than I did).
What should I do with these in the future?
