Are you hosting on your own machine or server? If so, you can add some buttons that are hidden such that only bots can see them and ban anything that clicks them.

I’m not sure personally how you’d manage it with html+css with no client side scripting, but my theory is to just move your ‘I’m a bot’ indicator button way off screen with css, or render it invisible and super small so it’s unlikely a human could ever find it.

I’m not educated enough to have an opinion that goes beyond what I like to type. I find C style to be the nicest.

I often use FreeBSD on a system with 2 gigs of ram. I WISH swap was useful. OOM killer is so overzealous the thing just kills whatever before even touching swap.
