I have a suggestion to hopefully contribute to solving this issue once and for all.
I am using the ConnectSafe DNS (have tried the old and new at this point). Both block certain photobucket pictures from loading. Thus, impacting the experience I am having while trying to browse safely.
I would like to suggest that photobucket be moved to the 3rd set of IP addresses rather than the Security and porn blocking section. I believe it should be categorized under "malware, porn, mature content, abortion, alcohol, crime, drugs, gambling, hate, sexual orientation, suicide, tobacco, violence." as to not cause inconvenience to others.
If you don't adopt this solution, please allow Internet users to view my pictures on photobucket domain! My photobucket account is on domain: s1082.photobucket.com
Thank you for your consideration!
