+From initial testing, [9%](https://github.com/jarelllama/Scam-Blocklist/commit/84e682fea95866670dd99f5c98f350bc7377011a) of the blocklist consisted of [parked domains](https://www.godaddy.com/resources/ae/skills/parked-domain) that inflate the number of entries. Because these domains pose no real threat (besides the obnoxious advertising), they are removed from the blocklist daily. A list of common parked domain messages is used to detect these domains and can be viewed here: [parked_terms.txt](https://github.com/jarelllama/Scam-Blocklist/blob/main/config/subdomains.txt)

 ## Why the Hosts format is not supported
 Malicious domains often have [wildcard DNS records](https://developers.cloudflare.com/dns/manage-dns-records/reference/wildcard-dns-records/) that allow scammers to create large amounts of subdomain records, such as 'random-subdomain.scam.com'. Each subdomain can point to a separate scam site and collating them all would inflate the blocklist size. Therefore, only formats supporting wildcard matching are built.
