I see a lot of comments here about using some browser that will allow ME to see sites I want to see, but I did not see a lot about how do I protect my site or sites of clients from being subjected to this. Is there anything proactive that can be done? A set of checks almost like regression testing? I understand it can be a bit like virus builders using anti virus to test their next virus. But is there a set of best practices that could give you higher probability of not being blocked?
