How would you get in-game feedback or do in-game polls?

For my game, I want to have a poll system where users can vote on a certain topic and I can access the data that all players who voted have provided. The polls would be shown across many servers and I would need access to all of the data from all of the servers. This could also be useful for a suggestions box or something like that. Is it possible or does anyone know how I would do that?
