I honestly couldn't care less if members sell submits, or give them out for free. Hell if you only got a site or two, pm me and if i have some time I'll run it through myself no charge.
However I know the consequences of forming a policy either way. So I'm going to boil this down to one rule on one single policy to cover the entire thing as well as spare a whole lot of trouble down the road.
Official Policy For Members Selling Submissions: NO BITCHING
If you are having your business rely 100% upon the performance of my tool than you are a complete moron. If you do 300 submissions during a month for clients and several of those sites see no effect and you get complaints from your customers and you decide to come to me about it....
"My customers are angry because your tool didn't work for them. Therefore I'm angry with you."
=
Me canceling your fuckin subscription and giving it to the next person on the waiting list so fast it'll make your head spin.
So as long as I don't have to hear about it, I'm willing to turn a blind eye to the whole thing.
