Cheating will be a problem when points or coins are worth $$$.
The security of the FAH network will not credit anyone that attempts to cheat. The amount of people with the know how to "possibly cheat" FAH's current security I'm sure is rather small. It will be a waste of their efforts. There have been a lot of claims that the system is cheat-able, however I have yet to see anyone suggest something that would actually make it through FAH security. Some of these claims might have worked a long time ago before FAH security was greatly increased.
