What are common user-side reasons for an 'invalid recaptcha token server error' on Gamefound?

Common user-side reasons for this error include temporary browser issues (like outdated cache or cookies), network problems that interfere with the reCAPTCHA script loading or token submission, using a VPN or proxy that flags your connection as suspicious, or aggressive ad-blockers/browser extensions that block reCAPTCHA scripts. Sometimes, simply having an unstable internet connection can also cause the reCAPTCHA token to expire or be corrupted before server validation.
