Depends on who owns the rights. Most UGC sites terms give them perpetual rights to distribute content as part of their services. Some take ownership of the IP. Most also let you remove your own content. If the performer owns the IP then they are completely within their rights to remove it where others infringes them. Whether that’s to protect their own commercial operation or because they don’t want those images in public anymore.
