Please stop your disruptive editing. If you continue to vandalize Wikipedia, as you did at Robert Koch, you may be blocked from editing. CLCStudent ( talk) 17:42, 19 November 2019 (UTC) reply

You have been blocked indefinitely from editing because your account is being used only for vandalism.

If you think there are good reasons for being unblocked, please read the guide to appealing blocks, then add the following text below the block notice on your talk page: {{ unblock|reason=Your reason here ~~~~}}.   Favonian ( talk) 17:44, 19 November 2019 (UTC) reply
