This one posts 2 times a day and hasn't commented in 22 days.

This user's posts are obviously not original and there are no references to the real authors, which means this is a case for @steemcleaners instead.

EDIT:

@csmedia is a similar case to the other ones and so is @sevillaspino. Your posts and theirs are very similar, the only difference is that they don't state the sources of the articles they copy, and you do.

Also, you could have made a single comment with all 4 users you reported instead of four. That is spamming!
