is it ok to copy & paste an entire article if giving the source? doubt it

I noticed Hive account@cheetah has not flagged any of the following posts despite all being copy & paste from CoinTelegraph.
https://steemit.com/steemit/@kalimor/japan-officially-recognizes-bitcoin-and-digital-currencies-as-money
https://steemit.com/steemit/@kalimor/bitcoin-revolution-hits-the-lonely-planet
several more can be found on on this account https://steemit.com/@kalimor
the user simply writes "Source: CoinTelegraph" at the bottom. that's it
probably Hive account@cheetah skips these posts as the word "source" is included in the post.
I doubt it amounts to fair usage though.

btw kalimor (as well as many other similar accounts ) are spamming such copy&pasted content with "introduceyourself"as one of the tags (that's how I bumped into them), which I think is yet another abuse that needs stamping out IMO.
