BT is UDP and you can write whatever you want into a packet.
Are you talking about changing source address in IP header? Most ISPs will drop such packets:

That's what I thought - but it turns out that not all ISPs behave well.

Right. Looks like I'll have to add some networking to my to-learn list. Thanks.
BCP38 is what you want everyone to implement
What kind of network are they using that lets them send forged source addresses? Also, a temporary solution in that case would be to use a blocklist of non-allocated ranges.
