@FxMasterGuru Thanks for the detailed answer. I start to get the point now of this blocking. Seems like a good tool but used sometimes in a bad way.
Well it is not good tool. It is not balanced.
For example you start a tread here. People abuse rules. The only way to prevent them from postin bulls*it is to block them. That is harsh. You would need button - dont post in this topic anymore. But this does not exist.
