Remove link if content got removed.#168

I ran into that a couple of times: I title looks interesting, click, content no longer there because removed by the user (or moderation).

Links should be rechecked if content is still there in interval (maybe only the first few days or in intervals that get exponentially longer). Like recheck 12h later, 24h, 48h, etc.

Yeah I’ve hit that too. Was that a Reddit, HN, or other kind of link?
