We don’t have a hard policy on this yet (it is a “gray area”), but what I would recommend is to avoid doing this. In general, we encourage people to use the tips to tip other creators in a natural way, not to send their entire tip grants/balances to themselves. (You can try tipping yourself, of course, but the point of these grants is to use them naturally and support your favorite websites and creators.)
Indeed, when entire tip balances are sent to a single publisher every month, repeatedly, this tends to trigger our anti-fraud filter. The filter will suspend your account immediately pending an appeal. Therefore, if you’re tripling up on this kind of self-tipping, then there is a significantly higher chance that you will trip the anti-fraud detection.
