As a solution, the link you suggested me kinda helped, but not really... My alternative solution for this was to implement Anubis anti-crawler, since I don't trust Cloudflare that much... My Forum is not on Fediverse yet and I didn't share with anyone and still I was receiving high numbers of clicks and inconsistent unique visitors... I told robots.txt to block every bot since well I'm still building the Forum and still I received one bot in there...
Hopefully with Anubis the problem can be at least minimized, but for anyone having a Forum... I suggest search for how to implement an anti-bot yourself since otherwise your bandwidth is going to cry for help. I implemented Anubis just today successfully, but I'll be monitoring the traffic of the site either way...
