As some of you will have noticed, there were 5 polls from the last 2 days by the same user. I appreciate the discussions is very quiet, but I have asked the user before not to run so many polls at once.
As a result I have removed all 5 polls as a result.
As a whole, there is no issue with polls. Anyone is free to create a poll to start a discussion, but there is a reasonable limit to how many and how often someone can make a poll or discussion; especially on a quiet discussions board.
