There's no "Quick Report" button on a user's profile, unfortunately. If they've posted a comment you can report that comment, and hope that that works out.

A more complicated way of doing it would be to email the LEGO CUUSOO staff. Here there is an option to contact staff. It takes longer, but if you are truly concerned then this is probably the way to go.
