OP I don't blame you. I didn't come to this forum to earn money, I just ended up in a campaign after posting here for quite a while. But people DO come here just for these campaigns and end up writing a bunch of bullshit. And accounts get sold to these idiots, which encourages farming, and the farmers don't make constructive posts...so it's a huge shitfuck all around.
I agree with you. But we need a solution, not to complain about it. DT trust members tried to curb sales, but it doesn't work. We need help from above (Theymos) to implement a policy change, which he will not do.
If my memory is correct I've read somewhere that this forum once had restrictions for new members - they could only post in a certain area. That might be a good thing to reconsider.
Apart from that, improving the quality of this board would be very easy if moderators would more frequently ban users that obviously engage in account farming or who only post unreadable garbage.
But I would not ban signature campaigns. I think if abuse is controlled, these are a good way to distribute small amounts of BTC to the crowd and thereby stimulate economic activity.
