What Discord servers do artists actually use for commissions?

I’m looking for active Discord communities where artists can connect with potential clients and advertise commissions.
I’m especially interested in anime-style / OC art, but general art communities are fine too.
I already use DeviantArt, so I’m mainly looking for Discord rather than another art platform.
If you know any servers that are actually active and worth joining, I’d really appreciate the recommendations! Small or niche communities are welcome too.
