What reddit forum limitation are you talking about?
Please read this weekend's tipping threads, and the related posts here in this thread, for the answer to your question.
And beyond those technical limitations, if you were to imitate meat_body_soul you'd really be losing out on about 90% of this type of promo's real potential, which we have seemingly stumbled upon in happen chance manner (as is often the case . . . like I said a couple of days ago, every cloud has its silver lining). Everything we do is a learning experience, and if we learn new tricks, why not embrace them? Even if they're the result of serendipity. Why limit ourselves? Wouldn't this be a great way to not only promote DigiByte without technical and policy limitations, but to also boost the DigiByteTalk forum at the same time?
