So who is the service that is shown to have blacklisted us? I keep hearing about it, but no one is able to indicate just who the service is. Opera uses 3rd party services and malware listings so just "Opera" doesn't help at all. I've scoured their website for the list of the services they use and I can't come up with a list on their site.

If anyone who uses Opera can give me a bit more detailed information, or even a screenshot for example, that would be great as I don't really have too much to go on to track down and resolve this issue. Thanks.
