Spam sent as musescore notification

As a serious music student just getting the hang of using Musicore, I did not expect to receive the notification pasted below as a notification from Musecore! ( It was followed by a list of internet links......) Has anyone else had a similar problem?
How on earth does a spam message like this slip through? How do I safeguard myself from this? Is there a proper procedure for reporting spam?
Thanks,
Minsterel
