User Pages
editUser pages are personal pages on Wikipedia. They are not indexed by search engines.
According to the guidelines, a user page is not a personal website.
"Wikipedia provides user pages to facilitate communication among participants in its project to build an encyclopedia. Generally, you should avoid substantial content on your user page that is unrelated to Wikipedia. Wikipedia is not a general hosting service, so your user page is not a personal website. Your user page is about you as a Wikipedian, and pages in your user space should be used as part of your efforts to contribute to the project. In addition, there is broad agreement that you may not include in your user space material that is likely to bring the project into disrepute." - Wikipedia:User_page
In short, anything Wikipedia related should be allowed.
