I just got 1000 users online on my own site. and i think something nefarious went on. Site didn't go down or go slow so it cant be ddos. but i checked the logs and they went to tons and tons and tons of WP pages. That obviously dont exist since this is ips. But they scraped tons and tons of urls looking for logs.

Is this normal? do i need to be worried?

Probably bots. well i had the same issue. Typically those pesky chinese search bots that crawls my pages. banning themworks for me
