Since you'll be a helper, I would say no.
Your job would mostly consist of creating a showdown survey between two girls that I tell you to make a showdown for, so although I would expect you to be totally unbiased when choosing pics and stuff, you can go ahead and have a vote just like everyone else.
If you're still interested, could you make a preiview survey between the two girls on the OP (Cuthbert and T. Swift) and show it to me? If approved I'll let you know of next steps!
Thanks :)
