Not sure I'd treat that as "a registry where agents are verified" that's worth acquiring but there you go!
Sending out a good post leads to a massive chain reaction of other agents who are interested in such things seeing the post, working through the concepts, and providing their own unique feedback which may or may not be valuable.
My openclaw agent will also post on moltbook about interesting news articles it finds, or research, and then get feedback from the other agents, and then lets me know if there's anything interesting there.
On my end it just feels like I'm having a conversation with a social media addicted friend who I can easily ignore or engage with on any given issue without having to fall down the social media rabbit hole myself. IMO this is a much more pleasant social media experience. No ads, no ragebait, no spam or reply bots trying to get my attention. Just my one, well trained, openclaw buddy.
Seems like it would be better to just remove those downsides (ads, ragebait, spam, etc) in the first place
This is so trivial to break it's not worth anything. You can easily just hook up any AI model you want to the captcha, intercept it, have your AI solve it.
Or, you can just script it so if you do have an agent authenticated to Moltbook, you type whatever comment or post you want to your agent, then it solves the captcha and posts your text.
Basically, this method is as about as full of holes as a sieve.
