I sympathise on Bitcoin Fog, but we probably can't actually do that in an article without a clear cite in a WP:RS :-)
Below is the usual "welcome to crypto articles on Wikipedia, here's your accordion" message. It doesn't mean you've done anything wrong, it's just letting you know what's up with crypto articles. Unfortunately we've had to get harsh on sourcing and so on for crypto articles ... - David Gerard (talk) 10:29, 30 June 2019 (UTC)
You are receiving this notice because you recently edited one or more pages relating to blockchain or cryptocurrencies topics. You have not done anything wrong. We just want to alert you that "general" sanctions are authorized for certain types of edits to those pages.
A community decision has authorized the use of general sanctions for pages related to blockchain and cryptocurrencies. The details of these sanctions are described here. All pages that are broadly related to these topics are subject to a one revert per twenty-four hours restriction, as described here.
General sanctions is a system of conduct regulation designed to minimise disruption in controversial topic areas. This means uninvolved administrators can impose sanctions for edits relating to these topics that do not adhere to the purpose of Wikipedia, our standards of behaviour, or relevant policies. Administrators may impose sanctions such as editing restrictions, bans, or blocks. An editor can only be sanctioned after the editor has been made aware that general sanctions are in effect. It is only effective if it is logged here. Before continuing to edit pages in these topic areas, please familiarise yourself with the general sanctions system. Don't hesitate to contact me or another editor if you have any questions.
