i have idea for new software you can release. GSA ref spam tool would be great for generating real targeted traffic. If you could make advanced ref spam bot which can send fake raferrers to most popular stat scripts like Google Analitics, Wordpress Jetpack stats, etc. - i can pay even $120 for this bot. Nowadays there is no working ref spam app on the market. Scrapebox ref spam doesn't work, xrumer ref spam doesn't work (with GA and most popular stat scripts) because these tools don't emulate browser. To leave fake referrer on most stat scripts - browser emulation must be implemented. I think you can make a bot like this, bacause your tools are the best in the market. Please consider this, i'm sure you will get a lot of customers including me.
