I don't think banning account selling would have decent effect since we are not able to detect many sales which are done inside this forum. If sales are encouraged outside this forum, our chances of finding sold accounts becomes slim.
We can actually. We're aware of plenty of public sales, and there's a fair amount of accounts that have been tagged for this very reason. In addition to that, the administration has more tools to detect these. As I said, the primary thing about the idea is the added
risk of a permanent ban (both sides).
But i would like to see banning alt accounts, which is main cause for selling accounts and spamming. Single person creating multi accounts and posting shit for few months and sell them with high forum rank to some newbie scammer. And also lending with bitcointalk account as collateral adds up to this queue for spamming, But happens mostly when the lender try to sell that account for defaulting and this encourages newbies to create multi account just for lending.
I think that having one or two alts is fine, and kind-of-encouraged in a free speech environment (e.g. a case where stating something may receive 'negative feedback' on your main account). The problem is the people account farming (we're talking about tens to hundreds of accounts).
I don't like the reputation is based on the number of days and posts rather we need the ranking to be based on some other factors which could actually determine the their reputation.
That's not reputation, that's activity.
Update: All of those have been banned yesterday already.
