Google More Sensitive Towards Automated Queries 2
Recently I have noticed that Google has become much more sensitive towards automated queries sent to it. It bans the IP very fast - much faster than it used to before. What’s funny is that the tool that got caught when I discovered it wasn’t even a site geenrator of any kind scraping the SERPs - it was a simple position checker 
Previously, it was possible to solve the problem by simply increasing the wait time between the queries sent to Google - not any more it seems!
Just another example of Google creating a problem for itself - if there was API for search still publicly available who would have queried the human interface SERPs directly?
As to the solution - I am now simply sending queries from multiple IPs instead of the same one
