Ok hear me out. If a whale wants to announce a pump anonymously, he can make a long expensive post on
http://bitcoinmegaphone.com announcing the date and time.
If the post is long enough (ie, expensive enough) people will know he's actually a whale and is serious. Then the post's permalink will get spread around the internet, helping to ensure the pump has a good chance of happening.
Thoughts?
Someone can spend 1 bitcoin writing an "expensive" message to let the fools buy into his "pump", they will pump bitcoin just to let the whale dump his coins at the peak over the first ones.
