Someone keeps uploading low quality images for popular Tamil movies

This user targets mostly Tamil language films. Whoever this person is, he/she keeps uploading these lower quality images and keeps replacing them as the primary image of the titles. Some titles in question are as follows: https://www.imdb.com/title/tt0376127/ (I recently changed the primary image of this title) https://www.imdb.com/title/tt0220656/ https://www.imdb.com/title/tt1305797/ https://www.imdb.com/title/tt4987556/ https://www.imdb.com/title/tt2302966/ https://www.imdb.com/title/tt0479751/ There are many more. Notice the images in question, they all have a similar pattern (being low quality/not being poster images/improper aspect ratio) https://www.imdb.com/title/tt0220656/mediaviewer/rm1706838016?ref_=ttmi_mi_typ_pos_23 https://www.imdb.com/title/tt0220656/mediaviewer/rm3255350017?ref_=ttmi_mi_typ_pos_2 https://www.imdb.com/title/tt0220656/mediaviewer/rm3473453825?ref_=ttmi_mi_typ_pos_1 He/she mass uploads these images tagging them as posters. Most of these images are not even posters but just stills from the movie. Whenever, higher quality images are uploaded and set as primary posters instead of this user's inferior ones, this person changes these posters back and even after the images in question are removed for justifiable reasons (for being low quality/not being poster images/improper aspect ratio), the user just keeps uploading them back and resetting them as primary.  I would urge the staff to look into this matter and kindly assist in stopping this person from tampering with these films' data as these are all very popular titles. As far as I know, this matter was brought up in this forum before on more than one occasion. Here is a post regarding the same issue https://community-imdb.sprinklr.com/conversations/data-issues-policy-discussions/low-quality-posters-for-tamil-films-in-a-huge-quantity/5f4a7a2e8815453dba9cafd6 However, this person has persisted and is actively resetting and tampering with these films' data and many more besides. Making it difficult to change the primary posters only makes it more difficult for us to change them back to what they should be, please take a note of that.
