Since the update when the Dev team has disabled Matchmaking system that let us queue 4-8-24man content.
High level Alliance raid especially from level 70 to 100 seemingly has a group of bot that queue together in big group, They usually botting the queue and cancelling repeatedly.

For example in one of the other day, I queue with one of my healer friend and me as a DPS, the queue start looking like this for a minute which is normal 0/3 1/6 1/15

Then this specific Loop start
-------------------------------
1/3 2/6 2/15 for 50 seconds
0/3 1/6 1/15 for 10 seconds
0/3 2/6 3/15 for 50 seconds
0/3 1/6 1/15 for 10 seconds
loop repeat
1/3 2/6 2/15 for 50 seconds
0/3 1/6 1/15 for 10 seconds
0/3 2/6 3/15 for 50 seconds
0/3 1/6 1/15 for 10 seconds
loop repeat
1/3 2/6 2/15 for 50 seconds
0/3 1/6 1/15 for 10 seconds
0/3 2/6 3/15 for 50 seconds
0/3 1/6 1/15 for 10 seconds
------------------------------------------------------------
Most prominent one is the Nier raid series where there seems to be a group of bots queuing and canceling repeatedly, And they come in odd number as if they don't want to be queue into higher-level content.
And if they dutyfinder actually brute force through them. I usually see them either cancel the pop or leave the moment before the map even load so we can't even see the name.
As of now. I am playing in Elemental - Kujata, This problem is running quite rampant that one of my friend wanted to finish Myth of the Realm series. We can't even get the lobby at all near daily reset, The bot always come at this time.
I have already reported this finding to Special Task Group to look into it because as of now. This exploit literally preventing people from getting into the match.

One of the main pattern I see that, The content that does not have people queuing for that and hoping to pull people queuing in Duty roulette to fill in the slot. I do not know how backend work but i reckon that these bot are pretty much preventing people from duty roulette to be fill into the slot.

I have came into conclusion that. Instead of we got ilvl exploit to be pull into Crystal Tower, but that exploit only affect people who run for daily quest. This exploit seemingly prevent other people from getting into the content they want to play.

Does anyone have any sort of this experiences at all?

**Edit
As of my test in my area. 60 70 80 90 Are all affected by these botting queue loop.
