Lost contact: Sapphu

[sirmeo.livejournal.com]

I'm trying to reach artist called Sapphu ( http://www.furaffinity.net/user/sapphu / https://sapphu.weebly.com/ ) -- they owe me a commission from like... almost a year ago. Last time I had any contact was in May, when I e-mailed their PayPal address (after using FA notes and the form on their site to no avail) they said they were setting up a workspace to be able to work on stuff they owe, and after that nothing. I've tried e-mailing again but have not received any reply.

Their dA ( https://sapphirelullaby.deviantart.com/ ) seems abandoned and tumblr account under sapphirelullaby seems to be in use of some advertising bot.

I also tried googling their PP address but found nothing useful.

Does anyone know if this artist is still active anywhere where I could contact them? It's waaaay beyond PayPal chargeback by now and that's my fault, but I had commissioned this artist in the past with no problems :(
