This list ranks the top 5 WordPress Plugin Directory apps classified under Spam blockerby the source marketplace's own taxonomy — apps appear here only because WordPress Plugin Directory itself tags them in this category, not because of any AppRanks editorial decision. Within the category set, ranking uses a Bayesian-ish blend of average rating × natural log of review count: the formula is rating × ln(reviewCount + 1), so a high-rating-low-review app doesn't leapfrog an established listing on a single 5-star outlier. The blend favors apps that are both well-reviewed AND have an established user base.
AppRanks does not invent a proprietary score for public surfaces — the rank shown mirrors the marketplace's published category position exactly, scraped on a 12-24 hour refresh cycle from the canonical WordPress Plugin Directory listing. The category lookup happens at request time and the page is cached at the edge for 1 hour to absorb traffic spikes; the underlying ranking data refreshes daily so the list stays accurate within one day of any source change. AppRanks does not editorially promote or demote apps based on advertiser or partnership status — the same blend formula applies uniformly across every app on this platform.

How does AppRanks pick the top Spam blocker apps for WordPress Plugin Directory?
Apps appear here because WordPress Plugin Directory itself classifies them under Spam blocker — AppRanks does not editorially add or remove apps from this category set. Within the category, ranking uses average rating times the natural log of review count (rating × ln(reviewCount + 1)), which keeps a single 5-star outlier from leapfrogging an established listing while still letting a very-well-rated mid-volume app rank above a poorly-reviewed giant. The page refreshes daily from the canonical WordPress Plugin Directory marketplace listing. AppRanks does not accept payment to alter ranking on public surfaces.

How often does this spam blocker apps list update?
Every 24 hours. AppRanks pulls fresh rating, review count, and pricing-tier data from each app's WordPress Plugin Directory marketplace listing nightly. Apps that lose WordPress Plugin Directory's category tag (e.g., a developer changes the listing's primary category) drop off in the next nightly snapshot. The page itself is cached at the CDN for 1 hour to absorb traffic spikes, so during a refresh window the visible list lags the underlying data by at most one hour.
What does "Pick if" mean on each top-3 entry?
"Pick if" is a data-derived recommendation that surfaces the most useful selection criterion for that app — high rating with deep review base means category default; free tier with broad adoption means budget-first pick; high rating with moderate review count means satisfaction-led pick. The framing is generated from the same rating + review count + pricing data shown on the card, not from editorial judgment or paid placement.
Where can I see the full methodology and audit scoring?
The full methodology — including the rating × ln(reviewCount + 1) blend, refresh cadence, conflict-of-interest policy, and the per-app audit-score breakdown — is documented on the AppRanks About page and the audit-score glossary entry. Every app on this list also has a dedicated audit page that walks through title, content, visuals, pricing, and category-tag scoring against the marketplace's published standards.
