S5H Blocking List
The list is an aggregate of abusive hosts and spam sources. We take the view that de-listing should be a simple matter once the activity ceases and rely on the end users to notify us once the activity has finished.
Mail or HTTP requests that contain spam will cause the source IP to be listed.
all.s5h.net is the single public zone for query and supports both IPv4 and IPv6 lookups.
Removal is simple, using the cleaned host, access www.usenix.org.uk/content/rblremove and removal will be automatic. If unable to use HTTP from the cleaned host then log a ticket via www.usenix.org.uk/content/rblremovehelp and a human will perform the checks.
