I remember when r/natureisfuckinglit was created, it's relatively new sub, there was a cool photo on r/earthporn, some dude commented "nature is fucking lit", someone else commented there should be a sub for this and the next person created the sub
I mean that would hardly hold up to a challenge fir inadequate consideration. The value of all intellectual property in perpetuity is easily worth far more than access to the reddit website.
Nah, you get to use the website. Access to a computer system in exchange for IP created with it is a pretty open and shut case. The value doesn't have to be equal, it just can't be unconscionable. Buyer beware.
