Questions about recruits

For example, Alex Kline twitter of yesterday:

He has mentioned the recruits that were at Temple-St. Josephs game, Seton Hall-Rutgers game (Jermaine Lawrence was one of them) or UConn-Syracuse game.

Why there is no mention of recruits attending our game?

And yesterday was not the exception. There are some threads about the recruits attending our games. And we only get the information thanks to our own posters.
But we never get that kind of information from guys like Kline or Zagoria (I´m not criticizing them).

Who gives them that information?

They get their info from being at the games personally. or by talking to a contact who was at the game, such as a coach or friend or someone.
