If a username is shown on twitch then it should be allowed in a poll without tripping the content feature. I often run fun competitions with my viewers where the results can be determined by a poll.

Unfortunately some of my viewers' usernames are not permitted in polls, even though they can chat freely in chat without censorship.

I don't want to add the 18+/Mature tag to these streams to allow a poll to happen and to have to change a username for a poll, while it can work, is both inelegant and makes the polling API almost useless.
