Please refrain from making unconstructive edits to Wikipedia, as you did at History of rockets. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism can result in the loss of editing privileges. Thank you. L293D (☎ • ✎) 23:37, 1 May 2018 (UTC)

Your account has been blocked indefinitely because it is being used only for vandalism. Furthermore, your username is a blatant violation of our username policy, meaning that it is profane, threatens, attacks or impersonates another person, or suggests that your intention is not to contribute to the encyclopedia (see our blocking and username policies for more information). We invite everyone to contribute constructively to our encyclopedia, but users are not allowed to edit with inappropriate usernames and we do not tolerate 'bad faith' editing such as trolling or other disruptive behavior. If you think there are good reasons why these don't describe your account, or why you should be unblocked, you are welcome to appeal this block – read our guide to appealing blocks to understand more about unblock requests, and then add the text at the end of your user talk page. -- The Anome (talk) 09:03, 2 May 2018 (UTC)
