The problem with “low-effort” is that it’s subjective. And sometimes it may be discouraging. KMEB’s Cottonfluffies originally started out as “doodles” over photos of cottonballs. Some people thought it was “low-effort” and “spam”. And yet, cottonfluffies ended up having their own lore and stories. Heck, I wouldn’t have written Milk if @kmeb had not continued cottonfluffies. Sometimes its just a matter of putting out something until you actually come up with an idea. It may seem low-effort at first but, if one keeps doing it, maybe something else could come out of it. 
Ideas aren’t borne in a vaccum.
Heck, even trying to define what may be low-effort could be divisive. Milk was a story that took me about a day to write, whereas some other stories I’ve written have taken weeks or even months to conceptualize, plot out and write. But does that make one story’s quality less than the other? Yes, I do believe quality assurance is needed, but its not that simple to define, whether its by writing or drawing.
