Websites often check your browser before granting access as a security measure to prevent automated bots or malicious traffic from overwhelming their servers. It’s a way to verify that you’re a legitimate user and not, say, a bot launching a DDoS attack. These checks can also help filter out traffic coming from tools like an ip booter or other methods that simulate massive requests to disrupt a site.I remember getting stuck on one of these checks while trying to access a gaming forum. It turned out my VPN was triggering the check because the IP I was using was flagged for suspicious activity.
