I have good experience at my night time too, but sometimes during the day as well. The key is to be persistent as hell and try way more than once. Why can't you guys solve this problem? Keeping bots off a website is trivial! Block the entire offending ASN if necessary. Or use something like anubis:

Anubis is a Web AI Firewall Utility that weighs the soul of your connection using one or more challenges in order to protect upstream resources from scraper bots. This program is designed to help protect the small internet from the endless storm of requests that flood in from AI companies. Anubis is as lightweight as possible to ensure that everyone can afford to protect the communities closest to them. Anubis is a bit of a nuclear response.
