(Sorry only just saw this!) Ah, I thought it was an mm opt-out. In general they're spawning a lot of AI sloppers to go off and send ever more fixes and causing ever longer days for us, it's quite a noticeable impact unfortunately. And often they're duplicative of already-sent fixes so you can see the conundrum with this :) So ideally we'd like a way to embargo these or have a maintainers-only view of them etc. so we can figure out a way of reasonably getting to valid cases. -- Cheers, Lorenzo
