How do you differentiate between legitimate new users with a bunch of existing users vouching for them, and a returning shitposter's 10000th spam account with a bunch of existing stealth-mode accounts vouching for them?

Although Reddit is not perfect, it doesn't seem to be a big problem there. Tor works and you can start posting as soon as you sign up.


reddit rate-limits new posters to something like 1 post every 15 minutes until they've accumulated some positive karma.


Yes, but they allow new posters to be anonymous by simply not blocking usage through Tor.
