This is a cool feature, but I feel like it's open to abuse and spam. Which makes me wonder, do you have plans for handling moderation and spam prevention in the future?
When a website is small, this is not a problem. As the website becomes popular, it will attract the lowlifes who have nothing better to do with their lives other than scamming, spamming, and trolling. I would hate to see this site overrun by those people.
Yes, I am aware of the scale of abuse. I fought it back when I was doing anti-spam and I see it every day at Cloudflare. The site has a bunch of moderation and anti-spam tools already built in and I plan to use them!
