Isn't it plagiarism?
I don't think so: images are excluded from plagiarism bans. So it's looks like loophole.
33. Posting plagiarized content is not allowed.[e] - Does this rule apply to images?
AFAIK no, it doesn't apply to images.
You hardly helped this guy by referring to this quote, because mprep's quote can be interpreted as desired only as long as he does not get tired of those who distort his words,
(since this is one of those cases where rule #23 comes into play). I am sure that even without his detailed
explanation today, it was clear that he then expressed himself quite unambiguously,
(therefore, it makes no sense to compare that case with the current one).
I'd like to add that I've seen escrow and signature campaign threads with copied lists of conditions too. Years ago I reported someone who copied a part of my service-thread to offer the same, and that didn't lead to a ban either.
This is strange, considering that, in theory, even an exactly copied thread structure or bbcode is one of the types of plagiarism or at least not gentlemanly behavior
(copied without your explicit approval). If you remember ... when I needed to use a style like yours (in my thread), the first thing I did was ask you about it.
