Right. It's kinda like when a bar suddenly becomes popular with a few nannies. Next thing you know, it becomes a 'Nannie Bar'. This is like the 'Anime/K-pop social network'. No biggie. It just happens.
You should try to be nicer then maybe you would have people that want to talk to you. also anime is really popular so yeah it's gonna have a lot of people. I came here because I saw an ad that said learn Japanese with anime characters.
