Hi Amir,
They put, “No liars or cheaters,” on their dating profiles because they are still caught up in the emotional repercussions caused by people they dated in the past that were liars and cheaters.
It’s best to avoid dating profiles that use this line. You don’t want to get caught with someone who hasn’t gotten over a past relationship. They typically use you as someone to unload their frustrations on and that isn’t what you are on a dating site for.
