I'm still able to submit more than once. I find that polleverywhere's sms based voting is a good way to get around this (but kind of annoying for voters).

Pretty sure that's because I didn't have that setting on before your first submission, as I'm not able to do multiple submissions.

Either way, we'll watch out in the results for suspicious behavior. Thanks for bringing this up.

Still seems to be a problem?

Weird. Not sure why that would be the case for you but not me. Well, in any case, we're planning on doing a lot of checks on the back end around this (b/c after all, anyone can submit a survey multiple times from multiple devices, etc., anyway).

Thanks again
