they just don't understand your language, that's all... you keep forcing your own language in their thread, so don't blame them for not approving you...
sorry, don't know you and seems like there is no mutual friends → seems like the most logical reasons for most people, including myself to ignore requests
^ seconded. Aside from language problems, that's the reason I don't approve you. Plus, you've started this thread which I dislike the most, as if you're the only one on the right side.
^this too, I've accepted a friend request by a friend of my friend by mistake a while ago. the profile was private, so I couldn't see the content before accepting. I ended up with a total whiner on my timeline
