Replying to View thread after it's been deleted?

One of my biggest pet peeves is replying/writing in a thread, leaving for a few hours, then coming back to find out it's been deleted and not being able to see why :(

Would it be possible that if you were part of the thread (aka it is part of 'My Threads') that you would still be able to view the thread, yet no longer be able to reply to it? That way it is still no longer active, but you would be able to read the replies that you otherwise would not have seen because it was deleted before you got back to it.

I understand if it was just a spammy thread there is no use seeing it, but some threads are 3+ pages and then they are just wiped out and I have no reason why. (ie skiierman meme thread, bummer to see that one go...)

just an idea, NS! thoughts/comments?
