But netdev@ and lkml@ are mailing lists for humans to interact, exchange ideas, send patches and review them. To me, an issue that was reported to netdev by a real user is _way_ more important than potential issues that a bot might have found doing crazy things. We need to keep optimal S/N on mailing lists, so any bots trying to interact with these lists must be very cautious and damn smart. When I have time to spare and can work on syzbot reports, I am going to a web page where I can see them and select the ones it makes sense to fix. I hate having to set up email filters.
