While there's plenty of other angles to complain about them, one of the more common ones is the fact that Cloudflare is just as happily providing service for the very same spam sites they claim to protect people against. There's plenty of blogposts that talk about this, but the one I'll give a link to is the one from Spamhaus[0], the guys who run the most popular DNSBL.

Spamhaus also mentions the main problem with their abuse form, which is that it forwards abuse emails to the hosting provider and the web administrator. They pretty much never do anything by themselves and neither the web administrator or the hosting provider have much incentive to disconnect spamming customers (since the admin is hosting it and the hoster usually stays outside of the risk anyway.)
