No. Yes. Not exactly.
If you create a poll and select For everyone, it will be featured in the main directory for all voters unless it's really NOT for everyone.
Polls aren't deleted, but we may re-categorize a poll as "For anyone..." instead of For everyone if they are not about popular subjects. However, that does not affect sharing, hash tags or searching. That is, your poll can still be found.
We will remove polls if they are using images reported in violation of coyrights.
(If you want to make sure your poll is featured For Everyone, make sure it follows the Rules.)
