God this, my number one share contact is my ex, who i broke up with almost 5 years ago, and literally havent contacted in over 4. This person isn't even a contact in my contacts anymore, yet still top HOW.
I used to have the same problem until i took the plunge and just banished everyone i didn't like out of my digital life. If i don't want to interact with them, i just make their contacts poof/block them
...did you not actually read his post?
