Beyond the obvious crawlers in your server logs there's a whole ecosystem of bots most forum operators have never heard of. PetalBot is Huawei's search crawler for their Petal Search engine. Bytespider is ByteDance crawling for TikTok's parent company. CCBot is Common Crawl building the open dataset that trains countless AI systems. DotBot is Moz's SEO analysis tool. MJ12bot is Majestic crawling for backlink data. GPTBot is OpenAI explicitly collecting training data. SemrushBot is the Semrush SEO platform. Most of these are legitimate. A few are ambiguous. Understanding what they're doing is useful for any forum admin.

Have you seen any of these in your logs? Any that behaved strangely? Any that you blocked and saw immediate drop in traffic from?
