Different corporations have different reasons for being listed on BLOCK SCORING LIST, For example: If you are Google, you will need to accept, manage and execute your AUP on emailed abuse complaints to abuse@gmail.com (in line with RFC2142 and just be a better netizen, be more ethical and be not evil) and you will need to do the other things you are not doing now (you already know what they are!) and you will need to stop doing the other things you are doing now (you already know what they are!) – If you are, for example: Amazon, you need to first VERIFY submitted email data, BEFORE dumping a ton of SPAM on victims and stop providing services and resources to abusers as money is not the be all and end all of everything.
