This ACL allows ANYONE to use your proxy to get to URLs that match your
misc_allow_list (unless they are blocked earlier).

Better would be combining the two acls in one http_access line...

http_access deny misc_block_list !misc_allow_list

... which reads block any request where the URL matches a regular
expression found in /etc/squid/block/misc_block.list UNLESS it also
matches a regular expression in /etc/squid/block/misc_allow.list. Just
be mindful of how regex matching effects your proxy performance.
