For a couple of weeks I've been trying out different services, at least 20, if not more. Naively I used similar usernames for these services. Log into a site today to add an article and check out the Limit Logins plugin to find that one of the usernames that was used in a service was an attempted. There were over 6,000 visits yesterday with multiple attempts using this service username. Not saying it's a BHW Service, I've signed up services all over the place. Just a friendly warning to keep security in mind, always. Keep it random.
