They need to either disable shout, yell, tell, and friend requests for trial accounts or place restrictions not allowing these on new accounts until they have at least 1 level 10 character, I have seen this work great in other games.

Is is a bit harsh? Yes.
Will it work? Yes.

Idiots will still go searching for gil on google but at least this way I wont have to deal with having to disable tells and stay on busy all the time just to stop the ungodly message and friend request spam, this has gotten way to far and needs to be dealt with now obviously what is being done about it is not nearly enough.
