So far I'm at 92 and I posted my webtoons since February, so its a hit and miss whether it goes up or goes down.
I post every Sunday though there was that one time I didn't post due to work and life, I think I lost a few? Other than that, I think it really depends what people go for when looking through the Discover section. Sometimes your subs will raise, sometimes it will lower, maybe one or two will give a like or they rate it up or down. Still make posts since my webcomic is pretty important to me, I just have it out there for others to read and give some thoughts :> I'm always open to em.
