AppRanks verdict
Generated from live marketplace data — refreshed daily
Hashcash is a category-leading WordPress app with a limited review volume. It is listed in the Security category on WordPress Plugin Directory, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. 5 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.

Protect Against Web Spam Typically various “Internet SEO Companies” try to leverage poor forum software protection against mass submission and create many worthless posts with links to a website they are promoting.
Some forum and blog software implement various CAPTCHA solutions but these have two negative aspects:
They annoy your visitors.
They provide a fake sense of security.
Today it is possible to buy access to API which solves any kind of CAPTCHA for just $0.70 per 1000 CAPTCHA images solved by a real human being. And do you really think your customer will be happy to try to solve one of these ridiculous CAPTCHAs?
Secure Against Brute Force Attacks Many modern applications are susceptible to brute force attacks. Take a typical login form, for example. Hackers can compromise account security by trying every possible password combination. They can also leverage a large network of proxy servers to paralelize this attack. Forcing their browser to work hard makes it too expensive and slow for hackers to perform a brute force attack.
