Can you explain in a little more detail what exactly did you agree to do and did you actually do it? Your OP makes it sound like you failed. Also how do you know the person in the chat screenshot is Developerx11? His excuse in the other thread was that there was an impersonator so I hope you made it certain there is no impersonator in this case.
I agreed to do two things: compile a Linux wallet and install a gambling script on his client's server. I tried to compile the wallet but I got a bunch of error messages. He said he would pay me
BTC0.01 for the attempt (will upload chat log soon). What I did do successfully was install a gambling script on his client's VPS. I uploaded the script and he said the client stopped responding after I did so. I never received the promised payment.
I know it is actually him because I was chatting with him on Discord because he sent me his handle to me via PM, and Discord doesn't use cell phone numbers the same way Telegram does.
