Artwork is also not allowed to be reposted without permission from the artist, so people should already be in contact/familiar enough with them to know what other platforms they use. If an artist doesn’t use any platform other than X/Twitter, now would be a good time to recommend they switch. Alternatively, you can also encourage them to post their own artwork here directly.
