It was discussed putting the forum rules prominently at the beginning of the forum and visually highlighting them, which was subsequently implemented. To protect photos provided by the forum from unauthorised reuse on eBay, the majority spoke for a clearly visible diagonal watermark in the middle of the image, since small or discreet watermarks can easily be cropped out. Mass post-processing of the existing image stocks is only realistic via specialised batch-processing software. In the background was the wish to preserve the forum as a place of mutual collector exchange and not as a free research source for fast sales.
