Good question. This was just a brain fart and I haven't thought through also I don't use twitter myself so I need to look at how the replies work. But the idea goes like this
Every 1st level reply with X number of likes for these tweets will be posted as a reply to these tweets
Redditors can either reply directly to the thread to create a 1st level twitter reply or reply to any other 1st level comment.
For every tweet created by redditors, I will also follow any replies to them and then post them back as a reply here to the original comment. This should be easy because since the bots are owned by us, I can just look into my own notifications.
