>>12279Whitelisting IPs and an account system are only similar if you're being super reductionist about it (unhelpful). Whitelisting IPs is far easier to implement and automate and more difficult to abuse in the long term while disrupting the regular users the least.
Obviously something like a post timer wouldn't be seamless for users, but that's only optional and if you're bothered by spam (CC is super slow anyway so that's probably not an issue). I think you could easily set up a system to reduce unwanted posts that would be invisible for regular users. Do you need me to spell out a specific solution? I'll only do it if they let me be a janny. Otherwise, I'm not doing their work for them.
Some solutions are not worth trying because they're objectively bad and the site admins have limited time and resources to work with. At best, you waste a bunch of time, and at worst, you lose a lot of users.
