@ルーミア I personally prefer to replace them, because otherwise I'd have to delete the sample and that'd damage the uploader's ratio, but as an user you can decide whether to ask for a replacement (by posting in topic #16765 or tagging it with replaceme, the topic is typically faster) or upload the full size yourself and flag the sample if it's already been approved.
