Im not 100% sure but ive gotten past one of these before, Disclaimer that i am not a coder in any way i pretty much winged it but what i did was copy paste the entire code section into a notepad and then ctrl+f searched for the url of the site because thats how it determines if its a copy, then what you must do is replace the url in the code with the url of the copy, for example say the original URL is “perchance.org/cool-generator”. and the copied url is “perchance.org/xgdbtydaey” you search for “perchance.org/cool-generator” and replace it with “perchance.org/xgdbtydaey” and since the url of the copied site is the same as the url in the code it SHOULD let you through, now again, im an idiot and 100% winged it but it worked for me so it might work for you.

sorry for the super long winded reply, i hope this helps
