As the title.
Should there be a new rule added where intentional removal of credits and watermarks from other peoples works be deleted?
Only thing i can think against it is if the original artist isn’t known. Usually someone in the comments finds it though
You should look up the credit first. Has the credit similiar works? Then leave the credit untouched.
If there are no results, then someone else might be trying to “steal” the works and want to sell as their own.
Only in verified cases you should remove the incorrect credits and add the correct ones.
