This is happening to me as well. I typed 2-3 LFGs for AC and got suppressed. This has got to be fixed! I have a very limited time to play the game and I need to find a group fast whether it’s on my lvl 80 warrior or Necro or my lvl 30 elementalist. I don’t have time to wait for the lock to leave.
If you are wanting to discourage this, GW, then fix the dungeon finder to where it is actually useful!
