The Republic of Cyprus National Betting Authority (NBA) blocklist grew from 95 URL entries in February 2013 to 2,563 entries in April 2017 — approximately 27 times its initial size — with entries specifying full URL paths rather than just domain names, requiring DPI-capable infrastructure for correct enforcement.

Implications
Blocklists that specify full URL paths rather than domains require ISPs to deploy DPI; where ISPs cannot or do not deploy DPI (as in Cyprus for HTTPS), path-based blocking is not enforced — circumvention traffic served over HTTPS avoids the most granular filtering tier.
Blocklist quality degrades over time (malformed entries, expired domains, duplicate entries were found); circumvention infrastructure hosted under frequently-rotated domains is more likely to evade stale blocklists.
