spam blocker

Spam Blocker matters only if the evidence supports a paid workflow around keeping sites trusted, protected, and recoverable, not a list of isolated fixes. The current commercial thesis is: Security, spam, and trust failures create business risk that owners struggle to triage. The entry wedge is to turn security and abuse signals into prioritized actions, audit trails, and recovery-ready reporting.
