Oisd used to have a hosts format list, put together from lots of other people's lists and deliberately excluding a lot of ad domains as mentioned. On 1st Jan the site has stated that it wil no longer produce lists in hosts format, making them available only in ABP format.
Important Announcement: Discontinuing hosts/domains -syntax
Starting January 1st, 2024, I will be discontinuing support for HOSTS and DOMAINS syntaxes. (Read: Stop building / providing them.)
The Pi-hole versions listed are the ones in which Pi-hole (re)introduced support for ABP's wildcard domain format in blocklists, which is why that is the minimum Pi-hole version needed.
This is at least the second time the site owner has switched off the hosts format lists; looks like this time they are staying off.
