On few of my sites running drupal and which had ALOT of bogus registrations and comments, all spam was stopped. So far it works. Different story once it get big enough to warrant specific implementation, but we are not there yet.
To be precise, right now it uses Dogecoin proof of work. I got it running pretty good with asm.js compiled scrypt miner code. In future I will need to solve scaling problem, as right now it runs with fixed 2 threads only. In future it will self adjust based on user computer performance.
Right now there is no payouts to webmasters, but this is next feature I am working on. It will be made directly to webmaster dogecoin address from p2pool I am running for this project.
I've been trying to get Hamiyoca's JS miner to work with mupool without much success. (Stratum is straitforward. I'm just dumb.) p2pool is way easier from the cursory glance I've given it. I'm surprised I hadn't heard of it before.
Any chance I could trouble you for an invite for jo.jcat at gmail? I'm already using proof-of-work to keep spam off my blog (josephcatrambone.com), but I wouldn't mind switching early to something more conducive. Hell, if the payouts are nonzero when they roll around, I might be able to strip the ads. Alternatively, what's the official way to request an invite? Sign up for the news letter and wait?
basic dashboard is out there, but payments are not yet. there is not much stuff behind login form yet :) so yeah, i would rather develop it further before letting people signup for it. till then you still can use it as a proof-of-work solution using keys generated on home page :)
I will definitely email invite codes to everyone once it is ready to go.
