In the [php] tag we have created a canonical for SQLi prevention. The accepted answer was converted to a community wiki answer. However I just linked to the answer and noticed the answer is again "owned" by OP.
I suspect OP flagged it to convert it back (not sure about that one though, be according to this it is one way). So my question is: when does a post qualify to be converted back to normal ownership?
UPDATE
As wax eagle commented:
CW is pretty much past it's usefulness, it exists to lower the bar on rep required to edit, with suggested edits that's sort of moot. The only thing it does now is prevent someone from getting rep for any additional upvotes on an answer.
Is this a correct assumption, meaning there is no reason for posts to be converted to CW although the community had a big part in a post and the auto CW option should be gone?
