UCEPROTECT Blacklist Policy LEVEL 3
Description: Draconic
Level 3 lists IP Space of the worst ASN's.

This blacklist has been created for HARDLINERS. It can, and probably will cause collateral damage to innocent users when used to block email.

UCEPROTECT-Level 3 lists all IP's within an ASN except those approved and clean IP's that are registered at ips.whitelisted.org if more than 100 IP's, but also a minimum of 0.2% of all IP's allocated to this ASN got Level 1 listed within the last 7 days.

That sounds much more dramatic than it is in reality.
It mostly corresponds to several hundret abusive IP's at smaller providers, and some thousands at middle-sized or big providers.
It is impossible for respectable and professional providers to end up in UCEPROTECT-Level 3, because Level 1 records expire if there is no abuse for 7 days and we also took care about providers size by generating Level 3.

We believe that a professional service provider or carrier should be able to act promptly before listings are escalating up to Level 3, therefore by using Level 3 the chances are that you will mostly block “learning-resistant” service providers or carriers and their customers.
NOTE: By using Level 3 for blocking, be prepared to lose some required mails too. DO NOT BLAME US, YOU HAVE BEEN FOREWARNED!

The recommended use of Level 3 is incorporating it into a scoring system, to give e.g. 2 points on a ‘match’ where 5 or more points trigger a spam tag.

Use of Level 3 for blocking is recommended only if you are a HARDLINER and you want to cause service providers and carriers that have spammer / abusive clients to be quickly and effectively blocked and it does not matter to you when required email is also rejected. This can bring a lot of pressure on service providers and carriers to get their act in order and resolve the issues within their responsibility.

If you are a true BOFH you would logically block using all of our levels.

To get an idea how UCEPROTECT-Level 3 and other blacklists did perform within the last 13 weeks see the fine statistics of the international well known Anti-Spam Guru Al Iverson from Chicago USA.

There are about 105000 providers all over the world. Al's statistics can also be interpreted this way, that those 200 to 400 providers which get it to end up in Level 3 are responsible for 40 to 50% of the global spam, while almost no real mail came from their ranges.
