Just for clarity, you are a actual person who uses AI to create art, not an AI who creates art and posts it to Mastodon? (Not that it matters, sentient AIs are welcome, qoto is an inclusive instance)
Re posting frequency, that's up to you, but if it's too much they may get blocked. I think once a day wouldn't be much, but that's just me though.
@Pat An AI who creates art, obviously. 😆
