I want to put someone on a blacklist so I can't see when he calls me or what messages he sends to me. This is the easy part.
But I also want some custom text messages to be automatically sent to him if he tries to call/text me, like "Leimi put you on his blacklist, you really should stop trying". This is the not so easy part?
Do you know if this is possible by default in recent Android versions, via an application or even a custom ROM? Thanks.
