Creating accounts is blocked too, if you don't have one and you want to make an edit, you have to go through some manual appeal process to request someone creates an account for you.
There are over 26 million EE users. Some of them are going to go to Wikipedia and make malicious edits because some people are just like that. But punishing everyone else for it seems like overkill to me.
Yes but then you have to wait in a queue for someone to create the account for you. That is, if they don't deny that too. Also they require your email address for this process.
It's just more and more barriers when all you want to do is quickly correct some information in an article you read. Very frustrating and counterproductive!
