I had suggested this way back when for classic, but I think it something we should consider for Threads 7.

Online Now should be more intelligent about spiders Instead of seeing Admin, Visitor, and 200 Anonymous you would see Admin, Visitor, GoogleBot, and 8 Anonymous. An extension on that would be to even tally how many pages the bot views during their visits and provide that extended information for admins.

I know with classic it would show hundreds of guests every time Google would crawl.

The only side effect I could see of this is a user using the bot name as their PDN. This could be countered by appending the reserved name list with the Bot IDs.
