Perhaps Force ghosts appear only to those who seek guidance and Kylo isn't seeking guidance from the good Anakin but the evil Vader (who apparently no longer exists). Maybe Anakin did appear to him and Snoke convinced him it was a trick.Didn't Ben's parents and even Skywalker tell him that in the end his father repented and even became a force ghost and another thing why didn't force ghost Vader step in and smack Ben in the back of the head the minute he started wanting to know about the dark side? This bugs me a lot, Kylo knows his heritage obviously then why didn't he now it turns out bad in the end for the dark side always? He talks to Vader or at least he thinks he's talking to Vader for guidance which is silly because Vader isn't bad anymore.
I'm guessing Luke in his training over the past 15 years or so has extensively contacted Anakin, Obi-Wan, Yoda and even Qui-Gon.
