There is an issue on the plagiarism thread that says is you change the words a bit but the meaning is the exact same it is also plagiarism. So he is saying no one can have those terms without quoting him.
Why is that a problem?
It doesn't
have to be quote tags. You can put it in bold etc and credit LoyceV, perhaps more clearly though than in your original version, and you won't get banned, if that's all you're worried about. However using quote tags for something that can be linked to on this forum is the more convenient way of doing this IMO, so why are you so opposed to that?
Sounds like you're trying very hard to invent a problem and diminish the plagiarism issue based on a few out-of-context examples. Plagiarism is a big issue. It's damn near impossible to plagiarize "accidentally" or whatever your point is here. You're doing it consciously if you're just copying some text that you didn't write, and not adding a reference to it. Instead direct all this effort towards making it as clear as possible that you didn't write the text that you didn't write, and everyone will be happy.
Still saying it is a set of terms that all people renting their signature should be able to use without quoting it simply because it is that good.
much like
"not your keys not your coins" I do not know who said it first.
Again, if all you're concerned about is a ban, you will not be banned for something in double quotes, even if that wasn't a well-known phrase. Something in double quotes implies that you're quoting. If you don't know the author that's fine. If you do - mention them. If you have a link - add a link. If it's a post on the forum - quote it or part of it. All common sense things to do unless for some reason you're trying to make it look like you created the text that you didn't create.
