Academic Research
Researchers, data scientists, statisticians as well as universities require a vast amount of data for their research. Allowing them to gather data via your IP address ensures that they can gather accurate data for their research.
Ad campaign verification
Most companies these days run online ad campaigns. These companies need to verify that the ads are displayed in the way they are intended to be. Bots often do not show the correct display of the ads. Accessing the web via your IP address will allow them to see the ads as they are displayed to regular internet users.
Brand Protection
Brand and trademark owners are trying to find websites that sell counterfeits of their products. Example fake famous watches or handbags, designer clothes, and shoes... To do this they need to access the web from different locations and not just their office IP address.
