What do I do if an artist from here took $325 of my money and left?

If it was throught paypal, I think you can ask for a refund on the app. also, report the user on the discord server, so they can ban them

It was boosty.

damnn, that's an issue, I'm sorry this happened to you:(

It was a bunch of YCHs, over a long period of time, and I found out today I was blocked by them on discord, I cannot get a refund due to boost being boosty, am out $325, have no idea how to fix or even deal with this, and if anything, I am unable to deal with this and am now just a cautionary tale. Kind of ruined my ability to even really trust artists without holding onto my money until everything is done... I can't even get onto the YCH discord because I keep getting an error from my device.

i’m so sorry this happened to you, the best you can do is report this artist (you can ask a friend or someone if them can do this for you since you mention you are getting an error from your device), these scam artist are the worst cause them are ruining the trust of a lot of people to honest artist, I hope you can solve this problem:(
