oh I can tell you that lately, hundreds of bots are very much visiting my website every day in volumes that I have never seen in the past... Unsure that's a good news though
The same thing is happening on one of my Blogger instances, the one where I publish about a very niche interest (old floor-mill buildings from the Romanian countryside). Most of the hits are coming from countries like Vietnam and Singapore, most of them associated with Android use, so I think it's a new-ish thing that Google Analytics' anti-bot/anti-spam algorithm just can't (won't?) catch.
