Update note: My report of these posts to moderator marked as Good, but neither user is banned.
I would not agree that the decision is correct, but it is not the first time that plagiarized posts are deleted without a perma ban.
I'm aware not all plagiarized posts leads to permanent ban. It's just a note that could be useful in the future or to save moderator time.
So this is probably a temporary ban for both members, considering that they have not been active for several days.
But looking at their posting interval, we can't be sure whether they got temporary ban.
