It happened after installing and using Bither and Bitpie app for hard forks on my phone.
you said it yourself twice, "It happened after using Bither and Bitpie app for hard forks" so why are you blaming blockchain.info for it?
you said you've been using bc.info for 3 years and no bad experiences yet so far
if it's really blockchain.info's doing, why they wait that long to screw you up
I suggest remember what you have done in the process of claiming those hard forks
there is big chance you exposed your private keys somewhere when trying to claim those forks
