It's also considered polite to discuss your grievances on thread closings with the mods in e-mail before you go soliciting opinions from the unwashed masses.
Rather than call the integrity of the mods into question publicly, you could have asked and been reminded that the "no OT poll" rule had been instituted shortly after polls became available, because the EN World population apparently could not police itself on the matter.
The thread was closed for reasons of policy. And the policy isn't arbitrary.
[Edit - not to make light of another poster, but one might expect a bit of sarcasm from a user with the name "Kibo". A good rule of thumb on the internet - when in doubt, assume the writer was trying to be amusing, sarcastic or ironic, and failed.]
