Awhile back, I started to get users from the .pl (Poland) domain registering en masse, three to five a day. None of them ever commented. It is not necessary to register to make a comment here, or to view the blog. To find out what was going on, I turned on the WordPress feature requiring registrations to be approved by me, and for awhile, I emailed the would-be registrants, asking them to confirm that they were real people, and to explain why they wanted to registered.
After a couple of dozen requests, nobody had ever replied, and I just let the requests pile up.
I have no idea why this is happening, what benefit those registrations could confer. I can’t even figure out what cost it might impose on me.
Just to be safe, though, I’m not approving those registrations, and I’ve deleted all of the registered .PL users with no posts (which is all of them).
If you know what this is about, or if you are from Poland and wish to register, or if you were previously registered but are not registered now, please add a comment to this post. I don’t want to restrict anyone with anything to contribute — but I don’t want to be taken advantage of, either, even if I don’t understand how it might be done.
