Another thing that could be done to help, as suggested on MLNT, is to click the modules of others that aren't dupers.
The problem with this is that folks are probably only likely to do this in a click/click trade which limits your max clicks per day to a max of 100 at Rank 10. My experience is folks don't generally just give clicks away. This gives dupers an advantage that is hard to overcome. Folks that actively run successful stores have a shot but that is about it.
One idea I had would be to have someone open up 2 dummy accounts. One would be called "I-am-a-dupe" the other "I-am-a-duper". Someone would then send friends requests to the appropriate accounts just to kind of say "We're watching you". I would doubt any of the requests would be accepted but if they were all the better. The other problem is finding someone willing to manage the dummy accounts and send out the messages. I don't really want that job.
