please don't blame whole blocks of IP addresses that don't belong together.
Since 5 days I try to get a subnet (/29) removed from your blocklist at "ipremoval.sms.symantec.com". But every day some IPs (partly unused, only one is sending about 100 E-Mails per day, but from none where sent any spam) have a "negative reputation" again.
It looks like you are blaming a /25 block that is subnettet and registered to different organizations in different countries. One other subnet is listed on a few RBLs but not mine.
Because of that one e-mail to hotmail was blocked and I am afraid that more e-mails could be blocked in the future (there are about 20 per month to hotmail..).
The whole block: 188.8.131.52/25
Please, give only spam sending IP a "negative reputation"!
