buy the subscription month-to-month from a re-seller since they make it mandatory to renew automatically if you buy it through the site itself.
I agree with >>7577 in that if you want to spend money to pirate, you should prob take that money and buy a few clips from producers to keep the content coming.
That being said, I wouldn't feel too bad about downloading clips from defunct studios or studios who are different and substantially worse from what they used to be.
Like if you want TickleCentral vids, tickling-videos is the only way to get them now since they took down their c4s store. Other studios like Tickling-Post, Ogre Productions and AllArtFetish haven't made a vid in years so I don't feel too bad about pirating their stuff. TickleAbuse and RealTickling haven't produced a good video in years so I don't feel bad about downloading those either.
If the studio is active and still producing decent content, which is v rare these days, think about buying their clips. Buy a month or two of k2s premium to download what you want from formerly great or defunct studios and then going forward use that money to buy clips from active producers to keep them going.
