The only way I could ever see a poll being a problem would be if you were
being dumb and putting it on a clan thread or something. Most of the other
threads on the forum are usually only temporary ones with short life spans
so there really isn't much need to be able to go back and edit them to remove
a poll or edit it. Also editing a poll after its created is pointless, if you're saying
that if you make a mistake it would be nice to go back and be able to fix it then
I'll say "hey you know there is a 'post preview' button, helps to check for mistakes
before you post a giant wall of text", proofreading is a thing.
