This user: https://stackoverflow.com/users/750613/nik has been adding "Thanks" or "Thanks in Advance" to the bottom of a question as a suggested edit and titling the change as "improved formatting".
I rejected a suggested edit and found another rejection:
However, looking more at the user it appears like it gets accepted more than it gets rejected, here are some accepts:
My understanding is that "Thanks" should be removed not added to questions. Is there a policy change? Or are people reviewing suggested edits not paying attention?
Additionally: since most of these edits get accepted the system will not prevent the user from suggesting more. Can the user be contacted? Or should the ones that accepted the edits have this pointed out to them?
