Bookmaker tracking technology.

The nearest thing to "the serial number of the device you are logging in from" that anything can capture is your MAC address - which is technically speaking a property of the network adaptor in your PC etc but for simplicity's sake is a unique number associated with your PC.

What do you mean by "4g sender device"?

Thanks longbridge.

I use a 4g router/sender to create a wifi connection, if I knew information wasn't collected about the router I could reuse them instead of buying a new one for each new person.

Hills had my IP address at home and at work tracked as well as my 4g on my mobile.  Any account I used on any of those 3 platforms was instantly restricted and in some cases closed.

I ended up buying burner phones for a bit but I just felt more and more like a drug dealer, all to get £100 on a football match or something.

Haven't bet with them in any shape or form for a long time now, but probably that's what they wanted to hear.

Your burner phone is my new tablet, new SIM, new 4g router equivalent @Wildcat, being able to use old 4g routers would save me quite a few quid in the long run but until someone could 100% confirm that the router info isn't harvested I'll keep buying new ones!!!
