Mastodon does likes and retweets, but lets you completely ignore them removing the stimulus. So, the difference with Twitter is that you're constantly notified that people liked or retweeted your stuff, and you see the numbers. When that information isn't displayed then you don't think about it at all. Having used both Twitter and Mastodon for a while now, I can definitely say that Mastodon is a much healthier environment. For me at least, it completely avoids the dopamine loop that Twitter creates, and I don't have the constant urge to keep checking it.
