I have too many fake users registering for my site, so I am turning off user registration. You still need to register to log in and post comments. So, if you want to do that (and you are human) contact me directly and I’ll add you to the site.
I also deleted all users from suspicious domains. If you find that you are no longer registered for this site, but want to be, contact me directly.
Since I get so few actual comments, I hope this will not be too much of a burden. If that changes, I’ll find a better way to do user registration.
