I didn't do it as a super quick burst, but in a space of multiple hours.
First because the proxy servers were super slow and second - I couldn't automate it - their servers had some kind of bot detection which would catch me calling the URLs through script.
Instead, I installed a browser extension which would automatically reload a browser tab after specified timeout (I've set it to 10 sec or something) and I opened like 50 tabs of the honeypot URL and left it there to reload for hours ...
Since they will fingerprint your browser. But it looks like they were people with low IQ, so you were fine.
