Got a new registered member on another WordPress based website today and searched adol77dai51 with Google. Lots of people have been getting their first registration as member adol77dai51. Spam perhaps? Maybe, but seems benign moreover. All the same I will be removing him/it (adol77dai51) from my user registration list.
adol77dai51 has registered on websites in all languages and all topics. With over 2,600 results in Google’s index for this term/word, he seems to be getting a lot of attention, bot or not. The e-mail used is email@example.com. It especially seems to favour WordPress blogs.
One of the search results led to several posts from adol77dai51 on a commercial blog for a loan-shark payday loan company. Way to go adolfodaine77! But, forget it.
