The easiest way IMO is to go to bpip.org and type the name in the search bar. Then if the name exists there's a button that says view profile, click that and it takes you to the profile.
The specific profile you mentioned is a newbie account with 0 posts. There are numerous profiles with the name and some other characters.
They're not a newbie though,
skeletonskeletor is the user that came up with the "magic internet money" slogan. There was a bitcointalk thread back in 2011 I think asking people for slogan ideas for Bitcoin. Then skeletor said magic internet money. That's the thread I'm trying to find and the comment where he said magic internet money but I can't find the thread anymore. Maybe I'm misremembering the way the username is spelt? I was fairly certain it was spelt skeletor but maybe it used different spelling. It's weird that when I go to the skeletor profile it shows no activity. Does anyone remember the thread I'm talking about the username of the person that left that comment?
