As mentioned above, you decide what you wnat to pay for your signature.
The first post below the OP shows the great informaitonavaliable on the forum which shows what campaigns are pricing each post by.
You can also choose to set a set pay for each user or to set a pay per post payrate for the signature camapaign.
Usually (these are estimates:
Legendary: 0.0003(yobit)-0.0011(gambling sites)
Hero: 0.0003(yobit)-0.001(gambling sites)
Sr Member: 0.0003(yobit)-0.0007(gambling sites)
Full Member: 0.0002(yobit)-0.0005(gambling sites)
Member: 0.0002(yobit)-0.0003(gambling sites)
Jr Member: 0.0001(gambling sites)
Newbie: ~0.00005
These are in bitcoin and are estimates. If you wish to ammend this then feel free
(Staff members are usually paid the same amount as legendary or hero members).
To run a signature campaing besides you be able to choose which rank you wanna to use your signature you will need escrow to people trust at you, and join your signature, setting a limit post will help and maybe offer some normal rate, seconstrade pays up to 0,02btc weekly i believe, being hero, with 35 posts, and they have plenty members.
Hero : 0.00041 BTC per constructive post. - payout changed as of 6/20 = 0.00041*35=
0.01435 btc MAX for hero in a week. seems your math off a bit, huh. my opinion for OP, just set MAX posts each day/week/month and just accept member which really have great post quality for avoid so many spammers.
My campaign - YoBit.net pays up to 0.042/week. You don't even need an avatar for it.
There isn't even a manager, it's all automated
It does have a manager, lol. Who does all the kicking and making sure the spammers are kept at bay?
Also, it takes a lot of posting to get the maximum post number- something the Yobit campaign has been famous for, and one of the reasons why I left. Way too many spammers; less today, but the 20 posts per day encourage people who post pointless things just for the maximum BTC per week.
True true. Before the 777 and Bitvest scandal they used to have a maximum of 0.05/week. But as you said it probably encourage spammers and so on.
It went down quite a bit! It was recently a maximum of 0.06
BTC per week from that campaign!
They also used to pay up to around 0.0013
BTC per post (so a user could earn a maximum of 0.13
BTC in a week)!
