Anti-trust is a big issue. You can not trust anybody, whom you might be knowing to be dishonest. Many people have a phobia of not being able to trust people. Especially those people who have bad experiences in the past with someone betraying their trust.
Whenever you have trust issues going on, know that people may or might betray you.
So, always be careful. Try to be honest, be truthful and gain the trust of all by being alert and good.
