Problem: We are banned from Afilias (.info/.biz) and Google (.dev/.app)
RDAP servers due to too many requests, causing timeouts.
Solution:
1. Added RDAP_BLOCKED_TLDS list in domain_checker.py
2. Skip RDAP for blocked TLDs, use DNS+WHOIS instead
3. Updated drop_status_checker.py to skip blocked TLDs
4. Removed banned endpoints from RDAP_ENDPOINTS
TLDs now using DNS-only: .info, .biz, .org, .dev, .app, .xyz, .online, .com, .net
TLDs still using RDAP: .ch, .li, .de (working fine)
This prevents bans and timeouts while still providing availability checks.
