I have a couple of wordpress blogs running, both 2.5. I noticed that within a week, I got a user named ralyjones25 registering. One blog is more like a website with no posting, so I deleted him, and he re-registered. Never posted. Then today, I get the same user registration on my other blog. Neither site is linked in any way. One site is brand new. SO, I google ralyjones25, and the username comes up on hundreds of sites as a recent registered user, but no posts or activity. Anybody have any idea what this person is trying to do? Is it a potential security issue? Someone trying to get links? Am I nuts? Opinions?
I would say it is a spam bot who got itself lost. Don't go mad about it. Just disable registration on your blog if you see it as an eyesore.
I get those too. I have ralyjones25 and adol77dai51 on a few sites. It seems to be very common and nobody seems have been harmed by it.
