But the evil ip just charge you a little amount of bitcoin and if someone will use a vpn or something like that they can abuse and create more accounts just saying
Chances are the VPN's IP is already evil, so changing to a new VPN won't (always) work. Just like any Tor IP has collected units of evil already.
There are no fees needed to pay just for registering a new account, unless the IP ADDRESS used by the user is found as a faulty address.
IP addresses "surrounding" an evil IP collect units of evil too. Theymos explained how it works in some of the old threads.
Your suggestion sounds too selfish and you are pretty confident delivering that suggestion, don't you?
As a normal user using your own normal home internet to register one account, you won't be bothered with units of evil. Your IP will be clean.
However, if spambots are able to use
4000 accounts to spam a bounty thread, I can only agree units of evil are too cheap!
people with access to whitelisted IP or non-proxyban IP will make tons of accounts and sell them off
Once these sold accounts start spamming and get banned, the IP that created them will collect units of evil again, making new accounts more expensive.
Most of the people who sign up here likely won't have to pay anything at all so anyone can create thousands of accounts from their home IP or any other one that hasn't yet been banned.
Isn't this a flaw in the units of evil system?
I wouldn't be against limiting accounts to one sign-up per IP as people would quickly run out of fresh connections.
As the proud owner of more than one account, I'd have to disagree. Using a few accounts keeps my main account more secure.
But I wouldn't mind if any IP starts collecting units of evil after signing up. Say the first 2 accounts are free, and after that each new signup adds one more unit of evil.
