I don't know if this is intentional or not, but just in case, I'll write this: if you open a page with many embedded images (including very small ones), some of them won't load, and you'll immediately get an error message "Too many requests from this IP" when you interact with the forum next. That is, as far as I understand, each image access attempt goes against the limit of 60 pages.
60 is for non-authorized users; for authorized users, it should be 600 within a minute.
I've increased it to 120 for non-authorized users, as the critical load from bots has significantly decreased for now.
