Just released the first of many code examples to automatically verify that our web-site displays the same complete data as within the Bitcoin Blockchain (this can be done manually very easily also without any technical knowledge using our site). The first example is one in PHP using simple_html_dom.php - https://lockedpost.com/validate/PHP-Validation-Code/ any code improvements are very welcome.

It's not possible to remove a message embedded within the Bitcoin Blockchain. Locked Post assigns a sequential number to the beginning of every embedded message ("L1,Message" - sequence number "1" for example) - this acts as a easy way to verify that the data has not been modified or removed (by allowing anyone to check the sequence hasn't broken and that the web-site content matches what is stored in the Blockchain [The web-site provides links to various services that allow you to view Bitcoin transactions and therefore the embedded data within.]). You can see every message ever posted here: https://bitaps.com/1K69sEhUwNgiva3xzPnToxS89dzydU7nPm I will also eventually release code to easily verify the web-site.

Back up! - nothing! it's completely open. You can only make a post when there are no other pending messages waiting to be confirmed in the Bitcoin Blockchain.
I had thought about creating some kind of interface/software to interact with the Blockchain and serve as a website would but through software. Not sure how you would get around the issue of having a central service wallet that funds it all (Unless messages get sent to my server and then the transaction is made, adding it to the Blockchain). A huge project I'd imagine.
I will be increasing the limit to 450 bytes per message soon - and through chaining you could have any amount of data you liked - but this is not my plan.
The only other issue really is that some trust has to lie with myself and/or the provider (I could reduce risk as much as possible by taking the necessary hosting measures - and then I would have as much control as possible - owning the main Bitcoin wallet [https://bitaps.com/1K69sEhUwNgiva3xzPnToxS89dzydU7nPm] means a lot) used somewhat as I could replace certain words with others or what have you! - but.. this can be randomly tested and would be apparent pretty quickly if it was to happen and people would stop using the service and probably jump ship.
