I wonder why there's so many weird domains being hosted on AS2? https://dnslytics.com/bgp/as2 (scroll down to Top Domains)

They are probably not actually hosted on AS2. Bad actors can inject garbage into BGP AS paths, either accidentally or deliberately.

    Bad actors aren’t blacklisted for repeatedly injecting garbage?

      Maybe? Sometimes? It probably depends if what they're doing causes operational issues. BGP is primarily a trust based system. Many upstreams have filters to limit route announcements from their downstream / customer ASes, but at its core, it is trust based.
