Why won't it let me follow this person on Instagram?

Well I'm trying to follow this person on Instagram and it won't let me. I'll would click follow, then it will say following for a second, then it would go back to say follow. This person did follow me and I asked them if they blocked me and they said no. I'm doing this on my iPhone 5 and I tried it on my old galaxy s1 and it did the same thing. I'm only following 101 people and I really need help.

Why is my sound changing on my iPhone 5?

Hi, we'll not sure if anyone else has this problem but I will have my phone on full volume and you know the lock and unlock sounds, they keyboard sounds are loud, and also siri and stuff. Now today I noticed that my sound was on full but, the sound that tells you that you activated siri would be very soft and that my lock and unlock sounds would be fine. ( also keyboard sounds were ok).So I went back and turned the volume high on siri. But then I noticed the lock and unlock sounds would go soft. This is very annoying. And so I reset the phone and I changed the sound to full and it was ok… And then it did it again. So does anyone know how to fix this?
