@Watcher I admire your ideas but in reality it's not possible. Getting the whole legit player base to stop playing? That means asking millions of people to stop playing. People get mad when the servers go down for just 30 minutes. I doubt they could last a week.
I do have to agree with what @ysmaelbp and @JoshHack are saying though; although it's not a "statement" (which is what you want), they are indirectly making a stand against spoofing (with the introduction of blacklisted apps). Alas, it's true what people say though: spoofers will find a way to overcome this roadblock in a matter of time.
Your comment about Fsutal is valid: I'm sure Niantic knows all about his spoofing activities. However, [opinionated remark incoming] Niantic could be using Fsutal as a marketing technique. Although most of Fsutal's content is "clickbait" and fake news, it still hypes up the community, which means more people downloading and playing Pokemon Go which means more revenue generated for Niantic. This technique is called "guerrilla marketing".
As defined by our good friend Senor Google "Guerrilla marketing is an advertisement strategy concept designed for businesses to promote their products or services in an unconventional way with little budget to spend". Although this technically was not 'designed' by Niantic, Fsutal is generally doing the marketing for them.
Obviously (and this goes for any company, not just Niantic) any company would definitely take advantage of free marketing, especially when done via media. This concept is called "social media marketing" (the act of marketing ones product or business via social channels)
Overall, I agree that spoofers should be stopped, but that your method won't work. Sorry
(Apologies if this was hard to read/understand: I used a lot of business terminology but I tried to define it the best I can. I take business as one of my subjects, hence my business rant )
