custom blocklist file

[logout]

We want to have our own custom blocklist file at http://xxxxxxx/blocklist.txt and include it in csf.blocklists on all our servers.
Is the following an acceptable format for csf.blocklists?

tcp|in|d=80|s=46.229.160.0/20 # flooding ADVANCEDHOSTERS-AS NETHERLANDS - do not delete - Sat Apr 22 03:54:23 2017
tcp|in|d=80|s=51.254.0.0/15 # flooding OVH SAS FRANCE - do not delete - Sat Apr 22 03:54:23 2017
tcp|in|d=80|s=91.200.12.0/22 # flooding VHOSTER-NET UKRAINE - do not delete - Sat Apr 22 03:54:23 2017

I've been looking at the existing blocklists and they seem to be in multiple different formats, whereas the documentation says it should just be a simple list of IPs..

Any advice is appreciated.
Thank you

I did some tests... and.. it does not work.

Would be great if the csf guys fix it
