Is it normal I am irritated by spammers?

No there is a method you just do not want to share it. Otherwise you would not be able to do it.

There is a method to these type of things. Since it happens a lot on this site it must be taught somewhere. The method is the key to reading the patterns.

Its like a math problem. You have the method and you can solve the problem. If not the problem is unsolvable. I read behavior I cant read personality in writing. The method is the key.

If everyone is doing it automatically that means it is a trained behaviour. So who trained you? Where did you get this method? If its that common it cant be something that everyone just knows. As well as that there is also people who do not know the key either. So where is it coming from?
