First off you should have a look at https://musescore.org/en/faq#faq-20657 to realize you've posted in the forum of a different site (also called MuseScore, so no worries, the confusion happens regularly) where no scores are hosted, nor can be commented on.
Then you can take your complaint into that "improving musescore.com" group or contact support@musescore.com directly.
