I vote that we keep things the way they are. Like everyone else, I get spam through various means all the time, and I hadn't noticed getting any more via this reflector. IOW, patching up this one hole will not substantially decrease my overall email vulnerability, and the solutions sound a lot worse than the problem.
If the concensus is to do _something_, I'd vote for the subscribers-only filter. The mailing-list software we use at Packetizer allows one to subscribe multiple From addresses but have mail sent to only one address. For example, I can subscribe plong@ipdialog.com and plong@packetizer.com so that I can send from either email account but only have mail sent to plong@packetizer.com.
