Advice: ignored commission request

[randomthings123.livejournal.com]

An artist on FA had made a journal stating that they would be closing commissions soon, so I sent them a FA note asking if any slots were still open. They said yes and asked me what I wanted for the commission. Unfortunately, their response came in the wee hours of the morning and I had to go away for the weekend, so I did not see their reply until 3 days later. I apologized for the lack of communication on my part and sent a response with the commission details. A full week passed, and I saw that my message had been read but not replied to. The artist says on their page to send another note if they haven't replied in a couple days, so I shot them a quick message just asking if they'd gotten my note with the commission info. That note, too, was read and not replied. It's been another 7 days, and in between then and now, the artist has opened a new account on a different site and been actively posting there as well as FA. I considered sending a third message (possibly on the new site) as I enjoy their work and really want to commission them, but I don't want to be pushy, and I am wondering if this is the artist's way of indirectly declining my commission. What are your thoughts?
