lingeringdoubts

I have a business idea that I want to try to validate, which involves periodically checking customers' websites using Selenium WebDriver, maybe once an hour. The service is similar to a link checker or uptime monitor (it's not a scraper and will only target sites that my customers can prove ownership of).

However, I'm worried that this idea is a dead end because my customers might have their sites behind CDNs like Cloudflare that will detect my activity as malicious and throw up captchas.

Are my concerns legitimate, and if so, any advice for mitigating this scenario?
