From what I understand you made a faucet site without knowing about request methods and all that programming stuff? I mean it's normal i guess it's a lot of simple to get an host and domain and use a script but i suggest you to read a little bit more about this stuff.
Now about your question it's nothing to worry about.That's how your script works.I guess this is the script that you use :
https://paste.ofcode.org/swMAy5UXKX6FDGSJJKmDq3
It has a kind of long if statement.What basicly it does if it can't find the required sessions for example it creates a session and sends user to index.php?er=antiblock.This is a normal progress nobody is cheating don't worry.
Thanks man. I'm learning how to code now but I don't know if that's a session from the code. Thanks for your information
