I am not a big fan of the way Ko-fi overly-compresses my images when I upload them, even when compared to Twitter's infamous compression. I am also concerned that Ko-fi is not equipped to compete with bigger alternatives like Patreon, and some people don't seem to like that it relies solely on PayPal as a payment option (although my own father, who is not very computer-literate outside of basic word processing and email-checking for work, was able to give me money through Ko-fi one time without having his own PayPal account).
It's probably best if I just prioritize uploading on Newgrounds (and maybe also YouTube for the occasional full-blown animated cartoon) and, not absolutely get rid of Ko-fi like I did with Twitter and Facebook, but just use it as a "tip jar" and not bother with uploading there--I'll just upload my art here and provide a link to Ko-fi in the description or something. I am in a good place right now with a "pay the bills" job and some freelance art and animation work, too, so it's not like I need to rely on Ko-fi for income or even use social media in general right now for anything more serious than "I want to upload some of my work when I have the free time and see how people react."
Nonetheless, like my barely-there YouTube account, Ko-fi is still there as a "necessary evil" to make sure my work is easy for employers or clients to find on the Internet, even if I don't outright enjoy the site like I do with Newgrounds, ArtStation or ZBrushCentral (thank you for not being like the crazies on Twitter or the wannabe-conspiracy-theorists on Facebook, btw). If you want to support my work, but I'm not open for commissions at the moment, you can still "buy me a cup of coffee" on Ko-fi.
