This happened a few days ago when I joined a e9s LOOT party through the pf that was advertised as [Duty Complete]. Here is the chattranscript copied from a screen I took so I could report it (if that even helps).
*Entering the instance*
[5]Healer 2: 21 sec cd please
[2]Party Lead Tank 1: kk
[7]Perceptive DPS 3: Was this a clear for 1?

[1]Me: Tank and healers E and W
[1]Me: It was loot I think
[2]Party Lead Tank 1: yeah farm
[7]Perceptive DPS 3: Says someone hasn't cleared

[8]DPS4: Healers usually east west
[3]Trap Tank 2: that's me
[1]Me: Does that mean its a trap party? xD
[7]Perceptive DPS 3: How far have you seen..?
[1]Me: I don't mind wiping as long as we clear
[2]Party Lead Tank 1: It's not.
[2]Party Lead Tank 1: Whenever you are ready Trap Tank 2
[7]Perceptive DPS 3: How far have you seen *tank job that Trap Tank 2 plays*
[2]Party Lead Tank 1: I'm tank swapping at NE btw
[2]Party Lead Tank 1: mark the healers pls
[3]Trap Tank 2: ive seen a video
[7]Perceptive DPS 3: That's not my question
[2]Party Lead Tank 1: chill bro we good
[3]Trap Tank 2: ive not done this
[1]Me: what is your prog Trap Tank 2?
*Perceptive DPS leaves instance and group*
[3]Trap Tank 2: i haven't done it
[1]Me: like, at all?
[2]Party Lead Tank 1: he's fine, he's in my vc
[3]Trap Tank 2: no
*2 replacement dps join*
[1]Me: How is this a farm party if a tank has not even ever done 1% of the fight?
[6]Replacement DPS 1: oh?
[8]Replacement DPS 2: This is a farm no? I hope people know the fight lol
[1]Me: yeah I'm out as well. I'm not really up for carrying a fresh prog under the guise of loot
That party lead had his pf up for a short while (dps are easy to come by). Someone else I know spotted the same party lead in pf later still hosting a e9s loot party but this time with the following description:
[Loot][Duty Complete]
SPEED RUN LOOT // TOWER ???? UP = KICK
