The last time they were on was when they made the post 6 months ago, so they're probably not looking anymore.. A lot of people have made posts like these in the past only to never come back to the site, and it sucks that they don't have the decency to update it, but hey, it happens. Little advice, you can click on the profile of the person who made the post and see the last time they were on the site. Hope you find an artist~
