This old issue (
https://bugzilla.redhat.com/show_bug.cgi?id=1177202)
keeps receiving spam every couple of weeks from a different account.
I've been trying to flag the spam comments as spam, and remove the
flags they keep setting, and remove their CC as well, so they don't
get follow-ups and get encouraged to continue spamming. However, they
keep doing it. It's really quite annoying. Is there any way it can be
locked or restricted to committers?
