The validators at Stratford didnt work - they seemed to be switched off. The

All the validators seem to be off. I expect they will stay that way
until shortly before stored value gets introduced. Of course that
will require validators at all station entrances which still hasn't
happened :-(

Do Travelcard Oysters need to be scanned on exit and entry?

No, but TFL seem to encourage you to do so as it probably helps
their stats.
