URL for Redbubble and Pinterest

My URL for Redbubble has to be https://www.bkaward.redbubble.com

and for Pinterest https://pinterest.com/BKAWardbyKatie

I couldn't have bkaward nor BKAWard nor katiebkaward for Pinterest at all, which means hackers are using this account name, and Capital letter means at Pinterest.

When I tried to open my Redbubble URL above, then the warning appeared that says this page might have virus and cannot open it, anyway.

And hackers put people in my redbubble URL always, like the below.

https://www.redbubble.com/people/BKAWard

Even a real URL won't change like above to click the link automatically.

Once I published this page, then all links are changed like into the last.  So that while i am writing, this page is also hacked enough.
