While I was searching on google for some old scripts, I felt on an old unset BtiTracker v1.4.7.
The exact date I found it: 18-07-2023(DD-MM-YYYY)
The domain is:
http://pleech.50webs.com/install/
I am wondering who had left this script unset for ~15-16 and kept paying the server (i found that this server costs $2-5 per month from the hosting company's website price list)
