Some updates. Apparently, making a thread in kbin will make a post on Mastodon, but not immediately. Here is the main page of my account on Mastodon (mastodon.social): https://mastodon.social/@CarrieForle@kbin.social

Under Posts tab, you will see this particular thread(https://mastodon.social/@CarrieForle@kbin.social/110717469552820707) and its replies. In contrast to my initial thought, posts on kbin seems to be ignored by Mastodon since I did not see my posts on my main page there.

On the other hand, Posts from Mastodon is transferred to posts (microblog) in seemingly arbitrary magazine on kbin, and again, not immediately.

Here's an example of a post from Mastodon: https://mastodon.social/@jensorensen/110719419446130679
Here's what it became on kbin: https://kbin.social/m/internet/p/859696/Latest-comic-Pick-your-social-network-socialmedia-internet-tech-authoritarianism

If you dig a bit in that account, you'll see her posts are posted in different magazines, which is weird since there is no magazine equivalent in Mastodon. I'm guessing it's on kbin's side that does this transformation, probably with the help of hashtag?

Also, posts that's too old will not be transferred. I did not find this post on kbin: https://mastodon.social/@jensorensen/110204027397694156 . Based on the time when it's posted, it's somewhere between April 16 and April 23.
