1,000 subs! It's actually a very low amount of subscribers.
It's a kind of bone, thrown to make people feel capable of getting revenue. They could have made it 100 subscribers, except I think they would have to spend a lot of time approving/reading comics, if they did that. They should have saved themselves trouble and made it 2,000, or even 5,000: the math makes it probable that a 5,000 subscriber comic will rarely hit 40,000 views.
Though it can vary drastically, according to posters here, the non-inflated stats should give a 1,000 subscriber comic around 1,000 views/comic. Assuming all subscribers are active, new views should give it just over 1,000 page views. But let's keep it simple for now. 1,000 subscribers with 1,000 views/update means a comic needs 40, yes 40, updates every month to squeak by and qualify for some revenue....
Who updates 40x every month? I am not sure there are ANY comics that update every day, but there might be a few in the 25,000 comics on Webtoons. It's a difficult level of output, unless the art is rough or the updates are only a few panels.
Most comics update twice monthly. Some do 4x per month. Some maniacs actually do 3 or 5 times a week!! However the 2x comics were encouraged and facilitated by the Webtoons rules of the past revenue program. Comics would dish out twice a month just to get by, and many would have one entry be a Q&A or announcement or illustration, etc. Now it is up to the artists--if he/she can afford to do once a month (due to subscribers/views) they can do that--since the page views, bringing in ad revenue, are king in the new paradigm.
So a person COULD succeed with 1,000 subs, and make $100/mo, but it is likely that at a weekly publishing schedule, an artist would need 10,000 subs to qualify.
It must be nice to have 300,000 subs or more: they only need 5x/mo. to qualify for the highest tier. Assuming those stats aren't inflated and the subscribers are active.
