My server logs are filling up with requests from a non-Google, non-Bing “meta” crawler and the spike is chewing through bandwidth. I need help understanding exactly which user-agents or IP ranges are responsible and putting an end to their drain—whether that means a complete block or a well-tuned rate limit. I already have access to my site’s and can modify it, so you’re welcome to supply the exact directives there. If a stronger measure (.htaccess rules, nginx directives, firewall entries) is smarter, just outline the commands and I’ll apply them or give you temporary access to do so. Acceptance is simple: after your solution goes live, traffic from the offending crawler must drop to a negligible level and overall bandwidth should stabilise. Plea...
