MysteryFCM, Thanks for the reply! Please bare with me as I am not very familiar with this type of thing but have been working with our Abuse department on this. We absolutely want to handle these issues as they arise so we do not get into this situation again. We believe we've taken proper action on all domains listed except for: trustbid.ws viejobueno.com warewz.ws e-service.ws alssayer.ws xsex.ws We were unable to find anything currently wrong with the domains. Also, some domains reported are not even registered now. Since new to this, I did look at many posts in your forums as well as http://hosts-file.net forum, but still have the following questions: 1. Is there someplace we can monitor our IPs and immediately take necessary actions so we don't keep getting blocked? 2. Does Malwarebytes IP blocking basically coincide with what http://hosts-file.net/ offers as far as a list of bad IPs to avoid? 3. Do you recommend any proactive actions we could begin taking in order to prevent this? Since we are a hosting company, it's difficult to monitor what users have on their sites. I know how forums work, so don't hesitate to tell me to do the research(just won't be as timely ). We just want to take care of this ASAP, so any direction would be much appreciated. Thanks, Paul
