What just happened? Can somebody tell me why some profiles are out of my reach? Could this be because they all got banned from this site?

I know I'm still new on this site, but what just happen is really weird, at least to me, anyway. I was going to give some Requisiten to my friend, Nikola, who's from Montenegro, but for some reason I landed on Fanpop homepage instead. Why is that? His Nutzername is F_F_F. He's a big Fan of Finnick's and his Motto was Finnick Fan forever. F_F_F is an acronym. That explains his username. Okay, I agree, he could find some better username, but still, it's really weird! But, wait, there's more! That's not the only case of a Profil out of my reach. The same thing happened when I tried to give some Requisiten to my other friend on this site, Ricky, oder Ricky_M. (M stands for Marsden, his last name!) Both of them joined this site about a week Vor and now I can't reach any of them. How is that even possible? What are the odds they both left this site in a hurry, without even saying goodbye to their friends?? I don't buy it! What is the real reason behind all that? Maybe somebody can tell me. I don't think they would quit Fanpop, not like this. So, what happened? Is it possible they both got banned from this site? How can Du get banned, after spending only a week oder two on this site?!? Can anyone get un-banned from this site? Did anyone who got banned ever got back again? What could possibly be the reason for getting banned?? Now, I know that my friend, Nick, oder F_F_F, is into Wincest (not my thing!), and that my other friend, Ricky, is from Canada, but I don't think they got banned for that! Can Du get banned from this site, if Fanpop moderators, oder people who run this site, don't like your username, oder your country, oder your taste in fandoms, oder even your user icon, oder if someone, like Ricky, was using his real name instead of a Nutzername on this site? Can Du get banned for posting stuff such as wallposts, oder Musik videos, in your own language? People in Montenegro speak almost the same language we do in Bosnia, as well as the people in Croatia and Serbia, all parts of ex-YU, so we all
