Beware - Ronmeru

I came into contact with ronmeru via discord, following their recommendation to contact them there as posted on their twitter, which is where i first saw them. I liked their artwork and agreed to pay them for a sfw piece. I paid the same day and they said they'd add me to the queue. Being used to putting confidence in artists, I didn't think much more of it as time passed. After more than a month I asked how it was coming along, since my commission wasn't more than a coloured sketch. They said they'd reset their queue the next day and get to work right away. A month passed, and I asked them again, to which they responded they'd do it tomorrow. A month passed and not a work, so on the 26th of november I asked for a refund as I was no longer interested and they had no proof they'd even started on it. They didn't respond and I escalated it to a paypal claim. They didn't respond and paypal gave me a full refund. During this time, they've shown activity on their twitter and discord server, blatantly ignoring my commission. I want to warn potential commissioners of this artist.
