Maybe introduce a Moderator role to the multi-user projects? That would require the project's moderator to clear the newly posted issues (whatever is possibly a spamming route there) before they propagate. As this is an additional friction point, some bad actors may be intercepted there (say, trying to clear a million issues at once or other equally ridiculous actions). Of course, by itself it won't stop someone from clearing a single issue to a million of "users". But may still help in id'ing such actors.
