In light of the ongoing garbage flood, I am curious whether the following would be possible to institute (and/or a good idea):
When a new/unregistered (or under-X-rep.) account posts an answer or question, it does not become public for 24 hours (or some other period of time).
During that time period, the post is viewable by sufficiently-high-rep users on some queue so that anyone with the opportunity can do some spam filtering.
I think that making it harder for garbage posts to become visible might deter trolls, at least to a certain extent. (But maybe I'm optimistic.)
