This has proven to NOT work...
Look at SeNuke and many other tools that are recurring as well on those same torrents.
SENuke is like that due to its price. $250/month? No wonder people are leaving their service after a month or so. Sure, they claim most of that is to support the captcha solving, but most who use it probably don't even spend more than $20/month with Decaptcher, I know I don't.
The Parish Lantern (Which I have a strong feeling is somehow linked to the developer of SENuke so that they collect money from those who don't want to pay full price and still keep them using the service to help spread the brand by word of mouth) is cracking SENuke for $30/month and pulling in all those people to use the service.
The majority of people don't use cracked versions of SB because it is just so cheap. You pay $50 or less and it's there for life with free updates. So if SB Forum Poster moves to something around $15/month, then there's no point in it being cracked or someone even investing the time to do it. People would just stick with the legit version since you'd waste more than $15 in time or money getting a cracked version.
Of course, value has to be added each month in order to make it worth the subscription.
