We recently noticed a fair bit of traffic on www.bbc.co.uk & www.bbc.com from a User Agent which identifies itself as "ByteSpider" (& has a @bytedance.com email address).
Lots of docs on the web state it doesn't obey robots.txt but ByteDance have told us it does:
> ...in the robots.txt files > user-agent:Bytespider > Disallow:/
Thought that might be worth documenting as it might be a recent change & several of us searched but found zero docs from ByteDance
