We pay 0.001*Activity/50 BTC weekly (max. 0.01 BTC).
your advertising money might be more efficiently spent if you changed your campaign to pay per post so people would want to post more while they are wearing your signature. (Or you could give participants the option of no post minimum or pay per post).
One slot on forum advertising tends to cost ~3-6 btc for ~8 days. To compare prime dice had their signature on almost every active thread when they were open to everyone and they only paid participants around ~25-30 btc per month
That does make this campaign unique. And most of the participants of this campaign do have many posts already on this forum, however some of them will be in old, inactive topics.
I switched signature campaigns today. The last payout of Bitmixer was on the 3rd of December, so I tried to complete the whole week; however, as I already swapped before, I already promoted 1 week in advance, so I don't think that is going to be a problem

I think this is a great campaign for people who are not very active on these forums. Now I think I do have more time to spend on this forum, I think it's wise for me to use a pay-per-post signature campaign. If this turns out not to be that effective as expected, I'll swap again. I still like this campaign, even if it only pays 0,00896 per week for me
