Invasive Steam Account Logger Website Removel Assistance

Their is a website called steamhistory.net that tracks everything, and I mean everything of your steam account down to your username history, profile pictures and much more. I looked into it and you have to write a few words (and you can’t copy and paste) for each single thing you want to ask them to remove, and they can just say no.

Please checkout this website and help me find a course of action to get my steam account removed off of here, as well as other guides for hiding your Steam accounts prior activity/identities, and if I should just make a new accounts (not worth it, steam games cost a lot).
