Poisoning the data has been around for at least a decade now. I used to work for a very large pricing analytics company that would track product pricing for Fortune 500 manufacturers.

We found on several occasions that some shady retailers would find the CIDR of the manufacturers corp networks and comply with the MAP policies on pricing if traffic came from them. Then when our bot went through with obviously generic AWS / Proxy ips we would see a much lower price that broke their agreement. That one was a fun realization for the manufacturers as to the level of shadiness some retailers would go through.
