StackOverflow / Stack Exchange / They didn't allow you to ask questions, post comments and etc.
The website www.stackoverflow.com is real waste of your time. I registered there and posted some questions. I found some similar questions to mine, but when I tried to add my questions or post anything in this post, the website prohibited my questions and posts. The moderators blocked my access as well as they limited my actions. It was unfair, but it was completely fruitless to argue with them about it. They could simply block you and that’s was all.
