It's not the first time this happened to me in freebitbox.
You can easily change this with couple of antibot verification.
1. We always ban all IP's assigned for hosting/vpn networks and IP's related to PROXY/TOR services.
2. Almost all users use dynamic IP's from ISP pool. These IP's can be blacklisted due malicious activity (spam/botnet/compromised systems),
so we cannot trust for any activity from these IP's. You can try reconnect until you get new dynamic IP, switch your connection (to mobile) or just wait several days.
