I'm currently at 1,000,000 inbox notifications. This leads me to believe that Webnovel either goes to 999,999,999 or to infinity and I'm not willing to put that much time into this. Also, my phone keeps on lagging on the app, I think that the massive amount of notifications are making it freeze. So, I'm getting rid of the inbox notifications.
On another note, I wouldn't recommend this challenge. As, thanks to this challenge every time I read a story. I now think to myself 'what comments would I be able to post so that it I get the most amount of likes possible.'
