Hello everyone
Regarding this issue about fake users and orders in WHMCS.
From 4 days i have a lot of problems generated by that spammer that i see now affect a lot of colleagues.
I ask for help at WHMCSservices and finally find a way to create a module that WORKS.
I have more than 12H with no spam. All issues solved.
I recommend to all that have this issue to install it
