Why would anybody change when they are posting for free? who told you to pay for the servers and staffs? why would I change my behavior if I could have 200 members post to promote my ICO for free? I'm hiring people to promote my ICO and will pay them after collecting money, if the first one failed, I'll launch another one.
Did you try charging fees per post from anybody with a paid signature?
Why member and full members need to wear signatures?
How many moderators could you hire if every body had to pay $0.5 per post?
Why the hell would I pay for the privilege of giving my valuable time and effort to post?
Of course, I don’t have a paid signature. But if pay-to-post were enacted only for accounts with paid signatures, this would cause two problems: (0) Reliably identifying such accounts. If accounts with paid signatures had to pay to post and others didn’t, then some signature campaigns would simply go underground.
Yes, my friend asked me to put this big, flashy link in my signature. Nobody paid me. Now, you need mods to search for accounts making unpaid posts with paid signatures, and perform adequately thorough investigations of them. (1) Account farmers would set their bots to spew garbage with no signature from new accounts, until those accounts reached a high rank. Then, they could pay a small fee for every spam bearing a colourful billboard. Depending on how the economics work out, that may be profitable for them even if their posts are deleted after
x average time. To tilt the economics squarely against them, the fee may need to rise too high for everybody else.
All in all, this “pay to post” idea sounds too much like the “e-mail postage” idea. Competent spamfighters were always strictly against the latter, on grounds that it would not work and it would create too much collateral damage.
The
only solution to the problem of quality is to measure quality,
viz., to enact some system for discriminating between valuable posts and worthless drivel. That’s what we now have.
You like a post then press a button : "suggest this post to sources"
That would be a boon to beggars—and most of all to farmers with lots of alts.
