I know one solution that would stop people from jumping sig trains now and then, so I thought I'd share it here and if Stunna likes it, he can think about it.
Reward Loyality
Give members that have continued to support PD sigs an extra satoshi per post or a fixed % extra in payment for each month they have continued to stay with said campaign. This would give people who respect Stunna and PD an edge over those who keep switching for a higher cashout whenever something else changes their payouts. This would also meam that Stunna would not need to update current payouts/post each time as people have started accumulating months within the same sig campaign and are already gaining more than what other sites offer.
This all wouldn't even br hard to do, just write down all names of thr ones that get paid and see if they decide to stick with PD again next month.
My sig as been reserved for PD ever since I joined the forum and I plan on keeping it that way.

Sorry for typos, wrote this in my phone.
