just a final thought on this...
The problem in the end is not  the copy paste stuff itself. As you say, there is sometimes interesting info in it. But it's the intension that matters quite a bit.

The c/p posts are not coming out of interest in Bitcoin or in a discussion about it. It's that sterile try & error pattern to get merits which disgusts me.
Like for example, if your wife tells you that you are a great guy, it probably (hopefully) comes from the heart.  It's something totally different when a car salesman tells you the exact same thing because he wants you to sell a car.

It's the intention and the person behind an action that defines that action and how we feel about it ...imo
