My blogs were recently hacked...working on fixing it

Two of my three professional blogs were hacked a couple of years ago. I reset the passwords and things were find. During the past few months they were hacked again, especially during the past few weeks. I have again resent my password and login to stronger settings to stop this. Thanks to the readers who have contacted me to notify me of these hacks. The content of some of these posts has been offensive and are not from me. I will remain as vigilant as possible, but the help of my readers is most welcome. In fact, emails from readers telling me that a post was made that looks inappropriate is usually how I first learn of the new hack attack. If this continues I will contact Blogger to see what other security measures might be necessary. Thank you for your understanding and assistance.
