I'll tell you what you did wrong. Posted on the Blockland forums.
If you wish to avoid douche bags, and not be flamed for the worlds dumbest reasons, then posting here is not a good idea. Act as you wish. Nobody can tell you what and what not to do. All they can do is type a bit of text that you can just skim past and ignore. You shouldn't worry about how your acting on the internet. The internet was made for people to be stupid, even though many get smarter each time they use it....
