I mostly agree but I also think the silence of not getting any commissions over a long period of time is honestly enough for most people to figure this out for themselves. It's also just awkward to tell someone you think they're at too amateur a level to sell their art. If communicated poorly, telling someone they don't have their drawing foundations down properly can accidentally be discouraging or downright cruel. And if you aren't known for having experience with making and selling art yourself but still make these kinds of comments at artists on a public forum then you're likely to get a reputation for being judgmental and patronizing.

There's also the fact that the FR art market is oversaturated, so an amateur still working on their foundational skills will often have better luck advertising elsewhere. I saw on kid make an easy 30 dollars via twitter with ms paint emote commissions last year while meanwhile their FR shop was nothing but silence and bumps.

But yeah, watching someone tell an artist on discord to price their art at 10 cents so they can take tons of commissions and meanwhile the artist can't draw a box... :/ (well maybe it'll be a learning experience for them to learn not to listen to the advice you get when asking random people on discord or on forums lmao)
