The first message says that images that are used under the "fair use" license cannot be displayed on userpage at all. This is a rule set down not by Moe, but by the Wikimedia Foundation. The rule can be seen at WP:FUC, mainly section 9. Second, Moe is right. Each user on Wikipedia has a userpage, but it doesn't fully belong to them. Wikipedia has rules on what can be said in userpages and rules on what happens to userpages if they fail to follow the rules. WIkipedia:Userpage is the policy you should read.
