Here's a short little "meanwhile" comic as a bonus, since it's been a while.
Oh, apologies about my personal website. My hosting is done by a friend with a small server, and... well basically every wordpress site in existence is now under constant effective-DDoS by AI bots trying to scrape all the data. They're not subtle about it, and just try to download all the pictures simultaneously. My server is too small to handle that load, so just reboots when that happens (it's usually down for about a minute).
The fact that it's near constantly down is just a product of how often I'm getting these requests.
Make sure you have a robots.txt file with a crawl delay set for all agents once every 30 seconds and that you are disallowing most of the WordPress directories such as WP admin, the media directory, etc.
I would also strongly recommend that you use a caching system if you are not using one. It's a lot more efficient to serve the same image a hundred times to different bots from the ram than loading it off your drive.
Just my personal opinions working in a web hosting environment.
I think that these AI scrapers might be smart enough that this doesn't really work though - at least if I were designing them I'd have them all come from dynamic IPs and not have any of them bother hitting the same target more than once. These things are very dedicated to acquiring content without consent, and if they're capable of causing problems for (say) Reddit, I'm not sure my little website is going to have much luck deterring them.
Honestly a better strategy might be to just glaze everything I draw.
Well, we are already using cloudflare, that's one of the other reasons why the site is so slow... I don't think the other two suggestions prevent a scraper from requesting the information from the server... I think they'd just make it more arduous for real people to access the content.
Instead of a tech solution, why not a legal one? Place somewhere in the website that refusal to follow your robots.txt is agreement to pay you x amount of money for your content. Then combine that with the dummy page solution the other person brought up so you can record the IP address, then take them to court so they pay you. Has potential to bring you a really really nice chunk of money.
I believe that there are multiple very high profile billion-dollar lawsuits being run against AI companies right now. I don't really have the budget to sue these companies.
Whoever their host is, they already appear to have some type of load balancing based on the four IPS. But I would also agree that a free cloudflare account does wonders for most WordPress users. But that's probably mostly because it filters out a shitload of bots and known bad actors. Just make sure you set up your origin certificates if you use a cloudflare account.
