You may want to start a conversation http://empireminecraft.com/conversations/add, with a moderator and explain how it looked before, any suspicions, et cetera.
Even though they're online, it doesn't mean they can auto-respond. They get messaged by many members of EMC and they can't get to them all much less instantly. Sorry but just wait a bit and you'll get a response.
You can wait for them to respond, but if it has been a couple of days or more, you might want to bump the conversation.
