I don't know how this is implemented in UI's but it seems that this rehosting occurs too easily.

If you visit someone's page and then.. oops its inappropriate.. I have to take quick action now before I get sued (and its easy to make mistakes and overlook something)

I'd rather have an explicit opt-in button 'Rehost' (or something) than having to opt-out by clearing the cache.

Or is this easily configurable already?
