Mass-block a user's followers to stop coordinated harassment

Coordinated harassment is an increasingly common operational risk for brands, creators, influencers and agencies: a single attacker can mobilize thousands of followers to reply, DM, or mass-report content, causing lost engagement, ad spend inefficiency and safety issues. The pain is practical and measurable — there are roughly 960,000 potential customers (brands/influencers/agencies/creators) and many lack tools to remove an attacker’s follower base quickly without collateral damage. You could build a cross‑platform moderation product that maps the follower graph of an offending account using graph analytics and entity‑resolution, then executes staged, auditable mass‑block operations with safety checks (sampling, thresholding, appeals) and exportable compliance logs. The MVP would focus on precise follower‑graph operations, a web admin UI, integration with major APIs, and a playbook for agencies; target ACV is $5,000, consistent with enterprise moderation tooling economics. The market is attractive now: platform fragmentation and creator monetization mean customers are willing to pay for unified, professional tools, and advances in graph and ML make precise follower‑graph operations feasible at lower cost. Market sizing supports this — $4.8B total addressable value and a market score of 88/100 with revenue potential 82/100 — but competition is medium and early trust is critical. To stand out you must deliver materially lower false‑positive rates and better auditability than existing tools, prioritize cross‑platform coverage, and take a compliance‑first approach to avoid platform TOS and legal risks. The core challenges are securing stable API access, preventing abuse of mass‑blocking features, and building initial trust with the first 100 customers, but if you solve precision, transparency and platform partnerships this can become a defensible, revenue‑generating niche in moderation tooling.
