I would suggst that questions that have been closed by the asker should be immediately deleted from the "open questions" list or, at least, be blocked for answering.
It has always been possible to add an answer to a closed question. Imagine that the asker selects an answer and you think it's wrong, you can add yours. Of course, it won't be able to be selected and get the points, but it will be there for those who look at KudoZ answers and glossaries.
But these closed questions should not be visible in the list of open questions, and this could be a bug. Our techies will need some links to help them to fix this. If you have them, please send a Support Request.
The same, IMO, should apply to questions that have been squashed. Why would they still appear on the list, and only after opening the link we are informed that we should not answer them anymore?
To me, this doesn't make any sense.
You're right, a squashed question should become invisible immediately from all listings, and it used to do so, I think it's a bug related to all the new changes in KudoZ. Same suggestions than for the previous comment.
