I was once thinking of a website that publicly stores encrypted messages for any bitcoin address but some smart guy explained to me that the public key of a receiving address is not known until it is used as an input and therefore using it would only work for some addresses or to be more precise, not with addresses as the users knows them at all.
My use case would be to send secret anonymous messages to anonymous recipients and I would totally love to see this come true but it seams not to be straight forward.
Spam comes to mind but the origin of this idea was exactly to prevent spam by publicly announcing to accept only messages that contain at least x BTC in form of a private key. My client could then sweep all received bitcoins and only show me those messages that meet the threshold and where sweeping worked.
Any thoughts if that would be possible after all?

Bitcoin free messaging service 0.00888000
Here's a way to send a message along with your Bitcoin tx, just send any regular amount down to 2 decimal places only, then include the code x.xx888 BTC followed by the number of your post here in 3 digit format on this thread where you have left your message , eg for the case of this post being the message then the amount to send would be x.xx888001 BTC - if/once 1,000 posts are made then it reverts to 001 again, just ignore any 1,000s & use the latest posts to see or place messages, the extra added (or minimum that can be used for this) is about 4.4 cents worth of Satoshis (Edit: to prevent spam txs)
I don't know if there would be any demand for this at all as usually one is in contact with who one sends a tx to, but in some cases one may wish to try & communicate with someone where their contact details are unknown, say the Linode haxers 128u4nNS2DCbPk61aNAXLUTsHZt5FAEtit (the robber's first bag of swag address) or perhaps Satoshi himself 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa (his creation block address, the first tx). Messages can be anything you can post here & are obviously public unless you've previously exchanged a crypto key with the recipient, this could also be done after on a certain date etc by another tx message though that would be public too
I don't suppose there would be too much demand for this, but if there is then I'll set up a web site to do it independently of the forum if wished, and replies here that are not messages are just skipped so people would use the next available post number for their tx message so best to claim one's post number first, compose the message & then send the tx with it in
If this thread would be better off moved to another section of the forum then please do
