EDIT : I just voted but why I can't see the results or anything on the poll ?

When creating the poll, OP selected: Only show the results after the poll has expired.
I voted yes. Reason being accounts are hardly if ever used for scamming or spamming. Accounts are rather expensive and with the community being quite cautious, escrow can be used or message are requested to be signed from an old address. It is very hard for any scammer to scam with an account bought. The change in posting times, style and sudden activity are clear indications. Spamming wise, accounts are usually marked with a high price and if any user scams, they would be banned from the forum, it's a waste of money. Farming accounts is rather bad but the community here requests high quality accounts for signature campaigns and most seller's don't spam up the forum due to this. Banning selling of accounts is too hard and would just push it underground. I personally sold several accounts and they were mostly used to spam constructively and none were used to scam. That's speaking from my personal experience though.
Yes, it is correct. Results will be shown only after the end of the poll otherwise people may change mind. So we will wait until poll finish to see the results.
