In the comments under Andrew Leach's now-deleted answer, you mentioned that you're referring to the following question:
Can one correctly hyperbolize the "take with a grain of salt" idiom?
Your deleted answer has the following words, and nothing more.
The origin is from the latin "cum grano salis"
You claim that another user copied information from your answer.
This is the only other answer there, exactly as it is posted, the whole thing. It has no edits done on it. And the answer in no way copies yours.
The origin you can look up and we can discuss it. It is used as you say and so its usage it real. You may find people misusing it merely to emphasize what they hear and not to discount or throw doubt onto it.
Particularly •"I heard that restaurant is bad, but take it with a huge grain of salt" would mean that the doubt was great and place was wonderful while the tone made me think it was a terrible place.
To me if the speaker is altering the phrase I would think that they may not know how to use it but take that with a grain of salt.
I don't see where the issue is.
If you're referring to an edit suggestion of yours rejected, I see no such thing on your profile at all. This is what your profile says:
This user has no suggestions
If you're referring to someone using information from a comment you posted there, then that is not possible either. You have not posted any comment there. Andrew Leach (a moderator of the site) has said that there are currently no comments removed from under that question.
So nothing was copied from you in any way.
