Didn't theymos a while back make it so that Juniors (or up to some other low-level member) couldn't vote on polls due to obvious abuse? Or was that just for a poll he personally created about a particular issue?
AFAIK one can only join a poll if s/he is minimum a
member Jr. Member. It was done to prevent abuse from a newly created account. I will update this post with some reference soon.
Previously, anyone could vote in polls. Now you must be at least a Jr. Member. This should make vote manipulation more difficult, though you should still not rely on forum polls for real accuracy.
This came in so suddenly. At least will there be an option to make a poll open to everyone in the future?
Why would you want to allow polls that can be easily manipulated?
So yes, if this information is not outdated then one have to be at-least Jr. Member to join a poll.
I just used my hilarious* account to test (which is a Newbie) to vote on one of my own polls and it allowed me to do so.
How it's possible? I have seen (somewhere) a Jr. Member was saying he can not see the options of a poll, he was also talking about images as well.
update:
PS: For some reason I can not vote on the poll. Is it another restriction for newbies?
I am sure we are missing something here.
