Fine, so figure out a way of preventing a single malicious attacker from poisoning an open survey by means of an auto-submission robot. Avoid penalizing multiple people behind a single proxy, and detect a single malicious attacker routing false requests via a network such as tor or a bunch of compromised hosts (he needn't be *running* said botnet: there are vast numbers of known botted hosts with open proxies running on them; he can use some of those).
Until you've done that, a scheme whereby survey responses are tied to single entities (like the registered-subscriber scheme) is needed.
