I do not know what you refer to as the regular address but unless the Wikimedia Foundation is the blocking entity such blocks are done by Foundation staff and marked as official actions in which case you can email answerswikimediaorg and receive a response generally within  hours it does not handle unblock requests at all The Wikipedia communities are selfgoverning The best you will get from the Wikimedia Foundation if you write regarding a community block is a referral to community processes like the Arbitration Committee or the OTRS volunteer response team You may not receive a response from either within  hours If you want a chance to speak to an administrator immediately your best bet may be to use the IRC channel While you would not be able to access the administrator channel there are several dedicated to Wikipedia where you might find administrators online at any given time
