syzkaller@...glegroups.com is a better one.
syzkaller-bugs@...glegroups.com plays more of an LKML role.

I don't mind adding syzkaller. Some time ago I wanted to contact
KernelCI, CKI, LKFT, 0-day owners, finding relevant lists wasn't
impossible, but for some it was hard.

For syzkaller it would be:

https://github.com/google/syzkaller/issues for bugs/feature requests.
syzkaller@...glegroups.com for discussions.
