I am not sure if OP made mistake by asking IE traffic, but he should know that only 6.8 % of internet users is using this browser (data from April 2019). I personally do not see any sense in such traffic, while leaving the possibility that there is a catch in his request.
I also know that some PTC sites have an option so that you can choose a type of device from which traffic is coming, but I still did not see someone offering an option of web traffic based on browser type.
The sense i see here is about exploiting those users who come with IE browsers, that's the only reason i see for someone to ask for IE traffic, do you know why only 6.8% of internet users use that explorer, because they don't know how vulnerable is that explorer, but if you go to exploit-db and search for IE you will find tons of exploits to bypass those users.
