1. What you seem to be looking for is a proofreader
Proofreader rates are lower than editorial ones in my experience, although that may not hold true for everyone but the reality is 160 - 200 dollars to proofread is waaay too little for the amount of words you claim to be putting out per month
Proofreading isn't just clicking on the red in your work, it's actually correcting your grammar, spelling and ensuring your words flow after the corrections are done
2. You're harming the industry when you offer low amounts
You can say this but at the end of the day someone of your size offering such a low amount will cause other people smaller than you to think they can get away with offering even less. Proofreaders deserve to be paid appropriately, don't offer exploitative rates especially now in the middle of a pandemic while people are worried about where their next paycheck might be coming from.
3. Even if you don't get punished, stealing art is a shitty thing to do
Like you're right you probably won't get caught for stealing Kawacy's art but it is still a shit thing to do and ethically wrong if nothing else. Atlus owns the joker design and probably won't care about some 2 bit writer on an obscure chinese website, but Kawacy who has ownership rights over the art piece itself might care and it's their right to do something about it, especially since you've exposed you knew it wasn't yours and took it because you thought you could get away with it on this very public and cached forum. Not the best legal move ngl.
This isn't really going to change you or anything, I only expect you to respond with "You misunderstand" if you even respond at all but it's for everyone else who reads this to know that you kinda suck for doing things this way. That's all, peace out
[EDIT for his later response]
Kawacy not doing anything doesn't mean jack, he has legal right over the piece itself although not the character.
The job you described is a proofreader and you can't really have one and not the others
Your rate for professionals is irrlevant. Standard rates are for all individuals doing a job be they pro's or not. You're hiring them and should pay them standard rate, your weird designation of professional and non-professional is just you trying to find a way to skirt around the issue of paying them too little. I did read the thread you arrogant individual
