Tips

• Limit sites to the platforms you care about for faster, cheaper runs.
• Increase timeout if you suspect false negatives from slow sites.
• Schedule recurring runs to monitor when a brand or handle appears on new platforms.

FAQ, disclaimers, and support

Is this legal? Checking whether a public account exists is generally lawful, but you are responsible for how you use the results. Do not use this tool for harassment, stalking, or any unlawful purpose. Comply with all applicable laws and platform terms.

Why didn't it find an account I know exists? Some sites rate-limit or block automated checks, which can cause false negatives. Raising the timeout can help.
