The gobbledy-gook websites do exist, I suspect mostly as a domain for hosting bot email addresses. The addresses would be legitimate, since they belong to a registered domain. Setting up a website often allows X number of free email addresses as part of the deal.
I see one user awaiting email verification now, and I am curious to see the outcome.
The ban on Ukrainian IP is not universal - it is total for one particular mobile bandwidth provider, true, and partial for another provider. So far, I have not heard of any bounced users being from the Ukraine, though, even from among our Russian Forumites.
The newest ban on a gobbledy-gook website has possibly yielded three thwarts within 24 hours, from what I can tell. All of those were trying, as their first touch on the website, to access a thread left by the bot that got through, that has since been banned. Apparently the bot registered another user *while I was instituting the ban* and it never got to post, poor baby.
