Phex uses a hostile list with about 100.000 entries for over 2 years or maybe more if I recall correctly... so its not that we just started spamfighting...
My tests showed that Phex handles your large list almost well... lookup times are a bit higher but are still in range and GUI memory spikes up quite a bit when scrolling through the list. The PATRICIA from Limewire will likely perform better. It might be worth thinking about integrating it, but it would likely mean that we would need to drop some features we have with IP rules now.

Phex is able to filter search results by hash, but it is currently not coming with a default blacklist of hashes. The user is able to define custom filter rules with hashes. But its should be no big deal to also use a default blacklist.
