Some fanpop members have previously tested this out, and their huy chương reappeared a few days after they rejoined that club. In some examples they even got a higher medal. I've seen it mentioned in other similar questions.

Unless bạn got your medal from adding screencaps, because they don't count anymore.
Aren't screencaps in older các câu lạc bộ still there, with the section just missing in các câu lạc bộ which were created since uploading screencaps was stopped? That's how it was last time I looked at the entire hình ảnh section, anyway.
Screencaps are still here, they just don't count towards medals. I think there was like a năm after the uploads were cut off that bạn could get a medal back that you'd earned for caps. Then... nada.
