Dead Links

I found articles with dead links which is annoying, or:

Outdated content

Content that is no longer correct (facts have changed)
Read through detailed articles such as tech. tutorials to find a hint in one comment at the very end of the comments list, that this is no longer valid. There are articles about Steem-Mining, for example, detailed explanations, but Steem mining does no longer exist! - This is really annoying that articles can't be updated or smoothly deleted :(

I don't want to flag someone as spammer who put a lot of honest effort into writing an article when it is only time that depricated the information.

I don't want to click on Flag/downvote only for outdated content, but what is the consequence? Thousands of people will read an follow instructions of how to mine Steem for example, until they get get so frustrated until by accident they find an information that mining is no longer working for Steem?

I guess this is a MUST upgrade necessary (improvement) for Steem in the future, what do u think?
