Going forward I do plan to add a question on sign up such as the "what does HDD stand for?" found in hddgruru forum. That should seriously limit the number of new spam accounts being generated. But for now, I think that seeing a higher number of members may actually encourage more legitimate people to join. No one wants to join a community of just a couple members, the number 500 looks pretty good though even if 400 are actually spammers. I seriously doubt that hddguru has 20,000 real members as shown either.
