it’s not jquerys fault
it’s just poorly written code
so what happens is that the code looks for links on the page and loads them as sources for img tags
then the img tag doing what it does makes a request to that src link to fetch that image, but in our case it was whatever link was on the page
so now imagine you open a pickem thread that has countless vlr links on it
the code loads those pickem links into img tags, the img tags in rapid succession makes an equal amount of requests to vlr thinking it’s getting an image. unfortunately, the requests in turn look like ddos/webscraping attempts to cloudflare causing cloudflare to ban your ip for a duration
