Free users can cheat to post polls?

Can someone with a free (ie not sponsored+) account test something? Apparently, Sponsored+ can now post polls. Apparently, you can switch to sponsored+, posta poll, then switch back to free, losing nothing, having ads for the 5 minutes it takes to post the poll, and then not seeing them again.

Sounds like a plan to me; can somoene try it?

(And I need a 6-apart suck icon...)
