While you can do this, it’s not clear to me that you should. There are a number of additional laws having to do with perjury and misusing goverment sites and while I would undoubtedly agree with you, were you to assert the application of those laws to the utilization of a user agent switcher is a ridiculous overreach, I am just as certain I have no desire to be in the hot-seat on the day we all find out.
Thus forcing everone to wonder why, if they believe some results are fraudelent, they are showing them to us at all.
