Sorry, too new to have experienced that (though I have been closely watching this forum for a year at least and I cannot for the life of me come up with similar thread/discussion, pls share)
Trivial cases of autobuilder checks I hope we are discussing. If so, we just agreed that AB while having limited ability to control packages submitted to it, lacks any degree of security control (if we'd start listing how many pakages have no maintainer as libxau6 we'd probably break this forum). True, but I know this only to be the case for -devel. Hoping this is not the case with extras(-testing)
