I would be add some fun with colors - modulate them. Not much, I think would be enough to change color temperature to warm or cold, but same color.

Content of modulation could be some sort of fun pictures, may be videos for most active bots.

So if bot put converted colors to one place (convert image), would seen ghosts.

Could add some Easter eggs for hackers - also possible conversion channel.

If you want to expand further, maybe include pages to represent colours using other colour systems.

is it russian bots? You basically created a honeypot, you out to analyze it.

Yea, AI analyze the data.

I created a blog, and no bots visit my site. Hehe

I highly advise not sending any harmful response back to any client.
