Our friend group has a 'people pleaser' and it's fine, most of the time. However, it has become a nightmare (and nearly destroyed our group) because when there is a person that needs to be kicked out of our group for lying/being manipulating/terrible behavior, this person defends them to the end and treats us like the bad guy. Passive aggression also accompanies 'people pleaser', because the person generally doesn't ever want to tell you what they really want or feel. It's extremely frustrating to deal with a person that behaves like this.
